$19 TRASHED Reel to Reel - Guitar Amp or Restoration?

  • I bought this vintage 1958 Telectro Model 556 Mono reel to reel tape recorder at a vender's mall for $19. The case was pretty well trashed, but inside I knew there lurked a tube amplifier, so I bought it anyway with an eye toward possibly making a guitar amp out of it. But some signs of life from the tape player made me reconsider parting it out. Now I'm thinking I might try to restore it. What to do...what to do...

    My brother was in Vietnam in 1965. While there he took advantage of low prices while he was on R&R. He shipped home many, many things. The UPS man came to our house almost every day during the summer of 1965. Some big boxes arrived one day. I did my brother a favor by opening them and making certain everything was in good shape after being shipped thousands of miles. I found an AKAI reel to reel tape recorder and two large speakers that had 12" woofers and small tweeters. I had a Fender bass cabinet with a 15" Jensen speaker in it. My amp had blown so I decided to see if I could use the AKAI tape recorder as an amp for practice. I have no idea what the wattage output was on that AKAI, but my Fender Jazz bass sounded great going through the tube amp on the AKAI tape recorder into my Fender bass cabinet. By the time my brother got home from Vietnam, I made certain that AKAI was working well, although I never did play any tapes on it. My brother took it off to his apartment and spent a fortune on reel to reel music tapes to play on it, when lo and behold, 8 tracks came out.

      Ironic that 8-tracks would supplant RTR tape, the latter being such a superior technology for home listening.

      Flaming is right, without some serious re-engineering to this thing and the addition of another head and preamp circuit to support the additional head, can't happen. I'm like an electron, seeking the path of least resistance. I think I found it in this case.

    My first guitar and amp was my dad's 1966 Teisco Del Rey EP10T plugged into a 1966 TEAC A4010S as a preamp which was ran through a 1967 Sansui 1000A stereo receiver containing this tube compliment: 2 x 6CW4, 3 x 6BA6, 1 x 6BE6, 2 x 6AU6, 3 x 6AQ8, 2 x 12AX7, 1 x 12AU7, 1 x 6BL8, 2 x 6AN8, 4 x 7591. The TEAC could be used to overdrive the signal into really thick fuzz. It was also LOUD. One day I pushed it too hard and toasted the majority of the tubes in the Sansui. Dad had the tubes (and something else) replaced and I was back in business.

I haven't found that sustain yet in anything I have been able to afford nowadays. You know when the amp is good when you can hear your guitar vibrating through it. That's the best way to describe it for me. Great job Brad

    This video reminded me of the good old days of just starting to play electric guitar. My mom had an old Sony reel to reel. I figured out how to use the VU meter levels and volume as a master volume setup for guitar. Have no idea what the model was; but it had speakers that mounted over the reel to reel chassis for storage. This was in the 70’s. I eventually got my hands on a pair of 4560 folded horn mid-low PA cabs that were loaded with EV Force 15’s. I actually plugged those cabs into the reel to reel with my ‘71 Gibson SG Custom. Sounded like shit; but, I was young and stupid. After that came a Marshall 100 watt 4-pronged half stack and the journey began. That setup was eventually stolen. I remember walking the SG home that night. Later that night, the Marshall half stock along with a mixing board I had was stolen. Man, those were some old days. 40 years later, got some fun toys now (Marshall JTM45, an 18 watt TMB Head, and an original vertical input JCM 800. Been through all kinds of different amps in between. Can’t even recall what happened to some of that older transitional stuff. Fender, VoxAC 30, Legend, Park, full circle and back to a trio of Marshall’s again.

    @MichaelBeeny Před 6 lety +3

    The coil you found was part of the record and bias oscillator. It used the audio output valve (tube!) to form an oscillator when in record mode. Nominally about 30khz, higher in better quality units. This provided bias to the record head and also fed the erase head. In up market units a push pull circuit was used at around 100Khz often around an ECC82. The higher bias frequency gave lower noise and produced less distortion and harmonics.

    • @TheGuitologist
      @TheGuitologist  Před 6 lety

      Michael Beeny thanks for the comment. I knew it had something to do with the bias for the head, but have no idea how it works. I need a schematic to study.

    Back in the day, Telectro was considered to be an entry-level, bottom-of-the-barrel quality tape recorder. In the didja know
    department, you can send Shure microphones back to the manufacturer in Evanston,IL, for rebuild/reconditioning. The
    mike you have is a Shure model 55S. An updated version of the 55S is still being made today for those who want a classic microphone look.

    Hey ! Nice. I was in the same situation. Therefore, I bought 4. I converted 2 into guitar amps, a grundig tk14, and a tk40. I left a tk125 original, because it was still working properly. I should change the power cord for one with ground cable. An the last grundig tk28 is a mess. A very old design, like a puzzle.
    I love the vintage sound through the 6x4" built-in speaker.

  • @audiotechlabs4650
    @audiotechlabs4650 Před 6 lety +1

    Many good ideas! What form would bring the most money? If restored, can you sell it? If turned into a low watt guitar amp, would you build a head or combo? Do you have an existing cabinet? Is there more of a market for a guitar amp than an old mono tape recorder? What ever you do, your loyal fans will be thrilled! By the way glad to see another video! Love ya Brad! Thankz

    • @TheGuitologist
      @TheGuitologist  Před 6 lety

    Wish i had been in this one when it was first posted.
    I had a Telectro R-R i found in the trash back in the early 70's. It was a cheaper version of what you have of you can believe that. It was a one speed
    I used it to record songs we were going to do in our little HS band. I had one R-R for each guy in the band.
    It was a wise decision to not repair the tapepart of that unit as they were pretty crappy when new. I think i see a permanent magnet for the erase head. That's your first clue it was really just made for the average consumer to novelty play around with at home. I'm sure the wow & flutter even when new was horrendous.
    Anyway, good thing you got your$20 back out of it cause even as a working reel to reel it is worth less than $20.
    To make it a tape delay would have been an interesting idea with built in flutter😂.
    Very fun to watch the whole process. Very much enjoy all your efforts and education.

  • @RODALCO2007
    @RODALCO2007 Před 5 lety

    Good resurrect for that tube amplifier, good sound. Those shaded pole motors with the extra take of winding to feed the amplifier is not always a true isolation transformer. Often it is a tap of winding at a specific voltage for the amplifier. That voltage could have been perhaps 60 Volts AC. When applying 110 Volts to the amp it caused the series resistors to burn up and tubes glowing like a light bulb. Old tube turntables had similar arrangements as well.

      The Guitologist . You should try to make one with the guitar cord output connected to the recording head via switching on the side of the reel to reel case.

      @SmiTTyy-sh8nc Před 6 lety

      It comes on a roll of all different diameters. There's a fixture that clamps and holds it also a glorified soldering iron with a flat blade to melt the two ends together. If you do replace belts often it would be a great tool for your shop. Should be available thru Grainger. I'll see if I can find it anywhere else. I'm just north of Louisville. 👍

  • @Erzahler
    @Erzahler Před 5 lety

    Hey Brad! Just watched this video. I would like to have seen this restored, but after seeing the trouble in trying to replace the belt, I can understand your decision. The manufacturer apparently didn't make this unit easy to service!
    I looked up the manufacturer of the Ceracap capacitor, American Radionic Company. The company WAS located in Danbury, CT. In 1987, the company relocated to Palm Coast, FL. It is now known as AmRad Corp.
    Except for the motor/transformer and the four-tube complement, this tape player/recorder looks very similar to an AA-5 design.

    excellent clarity and wicked note definition at the end there,i have one of these projects but have absolutely no gain
    and it was also a former reel to reel,it still has a potentiometer that does the volume and tone in one unit,idk if this
    attributes to the problem of having no gain.

    • @TheGuitologist
      @TheGuitologist  Před 6 lety

      I doubt that's why you have little gain. It's probably just a matter of the circuit being maximized for low distortion and high fidelity rather than guitar use. It could be you also need one extra preamp gain stage to really take it over the top.

    I think this would be kinda cool if you could make it a reel to reel tape machine with a DI input that you can use for guitars. Best compromise ever,

    • @TheGuitologist

      The way this one worked when in record mode, the output tube was driving the record bias and signal, so there was no output when a signal was injected. Would have required a redesign from the ground up.

  • @fullwaverecked
    @fullwaverecked Před 6 lety

    I like the way you think. It would be cool if you could fully load/record the reel tape with your favorite drum loops. Then you would have a vintage Amp with a built in drum machine. ;)

    I've got a sure 55 mic that was my father in law's. He restored it before I inherited it. It sounds nice and warm when mixing a guitar cab. He also left behind several tube amps. I've got a 200 watt stereo instrument amp, probably out of an organ. He serviced them for years at a local music store. I want to see what can be done with it. Are you game?

  • @ronme68

    Just as I started to doubt my first tube amp build would have any power you post this. Had an old tube amp from a record player that was built into a case of a film strip projector. It's a series filament with a 12AX7 and 2 50C5 tubes. This amp was modified 2 or 3 times the rectifier tube was replaced with a Federal ITT. 1005A selenium rectifier at that time the 35C5 tubes where replaced with the 50C5 tubes, the cap can was replaced with 3 caps and then selenium rectifier was bypassed with a silicon diode. At the time I could not find a schematic for this amp so I'm building an amp using the schematic for push-pull with 1 gain stage of the 12AX7 and the other as a cathodyne phase inverter. The schematic I'm using is just called AC/DC Amplifier. For this build I'm looking for a clean amp for a acoustic instrument.

    • @TheGuitologist
      @TheGuitologist  Před 6 lety

      ronme68 should be ok for cleans. PP with just one stage of preamp is almost a waste. You could add a little op amp up front for more oomph.

  • @tubical71
    @tubical71 Před 6 lety +1

    As much as i like R2R machines, it´s always a paine in the arse to change capstan belts on home taping/semiPro machines. It usually needs a close to complete teardown of the machine/drivetrain....
    only the top pro machines are some sort of easy an xchange when it comes to beltchanges. Usually you lift the "playdesk" up and the electronics are completely seperated underneath. Instant access to the all the moving parts and all belts without any disassembling...:) change the belt(s) close the desk and here we go again.

    It would be awesome to see you convert an old cassette machine into a tape delay with variable speed. Many people have done this with the Marantz portable cassette I believe.

    • @TheGuitologist
      @TheGuitologist  Před 6 lety

      I saw that. None of them knew who the hell I was...even though Bruce Egnater is in one of the amp groups I frequent. It was good for a laugh. What's his name, Phil Knight, was asked about one of my videos too not too long ago. I only know this because one of my viewers pointed it out. He called me "the guitar-ologist". :D

  • @ka7hqp182

    When I saw that Victor speaker, I thought that you should be looking for the Kalart/Victor 16 mm projector model 70-15 (15 watt tube amp), or a 70-25 (25 watt tube amp), that was what normally drove those speakers. That would really sound good.

  • @DAVIDGREGORYKERR
    @DAVIDGREGORYKERR Před 6 lety +1

    What about building a PWM amp to replace the amp that tape deck and possibly use the tape mechanism as a tape loop reverb, a NE556 half used as the clock the other half used as the Pulse Width Modulator clocked from the first half driving MJ3055 TO3 case transistors driven via a BD131 driver Transistor whose collector connects to the base of the bottom MJ3055 as well as a 10 K resistor to VCC and a 47R resistor from the emitter of the BD131 to GND and the output from the MJ3055 goes through a lopass filter back to emitter resister via a 47K resister, the base of the BD131 gets driven via the second half of the NE556.
    I guess you are wondering about the two MJ3055 transistors well a 1K resistor connects between the VCC and the base of the top transistor then to the collector of the bottom transistor via a IN4007 diode and a matching IN4007 connects between the emitter of the top transistor to the collector of the bottom transistor, the emitter of the bottom transistor connects to GND or negative the output to the speaker via a 10,000uf electrolytic connects to the emitter of the top MJ3055 and also connects to the lopass filter that feeds back to emitter of the BD131, I would have attached a diagram but CZcams doesn't allow you to add attachments into the comments.

    • @TheGuitologist
      @TheGuitologist  Před 6 lety +1

      The tape mechanism could be repurposed into something like this, but I'd need another head, for one, and I'd still have to figure out how to get that belt on.

    A cool guitar amplifier could give someone a ton of fun and experience for years to come. A restored reel-to-reel will basically just sit there unless you happen to have a ton of reel to reel tapes. In terms of benefit to the world, i think a sweet amp would make more sense.

    • @TheGuitologist
      @TheGuitologist  Před 6 lety

      In some cases I do that, at least on parts of circuits, to help visualize what's happening, but in something like this, it's more a matter of deleting what I know for sure doesn't belong and putting in there the stuff I know should go, then tweaking around the issues.

  • @1inDnile
    @1inDnile Před 6 lety

    I say make it into a Recorder\Guitar amp and delay echo unit and maybe add another one or two play heads like a Watkins copy cat with a feedback control, I love this I grew up on these recorders I have a collection of similar tape recorders.You know you can do it.

  • @chokkan7
    @chokkan7 Před 6 lety +1

  • @butre.
    @butre. Před 6 lety +1

    I wouldn't bother restoring the reel to reel machine, but I would make it functional again. maybe make it dual purpose so you can put samples on the tape mechanism or use it as a tape delay. I'd definitely restore the model 55 though

  • @ColoradoMiniCrawlers
    @ColoradoMiniCrawlers Před 3 lety

    I have a similar reel to reel but it stereo unlike this one. It currently doesn’t have tubes in it. If I only intend on using one channel as a guitar amp could I only buy tubes for one channel or does the amp need all of them to function properly?

    No doubt, make an echoplex-ish thang. With the price of effects being as high as they are, you could swap out to some general/generic tubes and make some player or yourself totally psyched. Or... make it an amp or go back to orig. Lol, was that helpful? I feel your pain with this decision. Good luck with your back duder, walking is great back healing therapy

  • @ETILHK54
    @ETILHK54 Před 6 lety +2

    I haven't watched the whole thing yet, but answering the question, if i had as much amps as you do, i would probably go with the restoration of a tape machine, because as far as i understand amps aren't going anywhere, but this thing looks like it might be interesting. I'm myself fighting with a tremolo pedal right now for about a week, specifically a buffer gate section which doesn't want to switch transistor properly without polarised caps, and i don't want to have a polarised caps in there, yet with polarised caps (non pun intended) it works perfectly, so maybe i should just proceed with that. What do you think? Obvously you don't know exactly what is going on there, but even some general wisdon might be useful.
