Finally found a useful/good cover! Great stuff!!

A better way to implement this is with a smaller 100k pot. This gives you get much better control of volume levels especially for low volume settings... But to use a 100k pot you need to do a simple mod to the pot itself so that it disconnects itself from the circuit at full volume. The trick to do this is to open up the pot and scrape away the end of the pot trace so that when you rotate the pot to maximum, the wiper completely looses contact with the trace and the two connection leads become disconnected. The transition from in the circuit to out at full volume is hardly noticeable. And this mod allows to you get infinite resistance (instead of only 1meg) between the leads at maximum volume, but a much more useable volume range. Like you said, the 1meg pots are too hard to control volume levels.

yes dirty bends is what i searched for. i knew how to do it. guess another 30 years and i might get it to sound good ever time. zak wylde master at it. beautiful example of it in the Everybody wants to rule the world solo at the end. 💪🏻

That is the worst guitar face ever. You look like you're trying to eat your own head.

really clear as to what is a bright cap and its modifications. Thank you !

Your channel is so good!

My hats to anyone willing to work those tiny components. Those were some great mods. Do have any suggestions for a Blues Jr? I rebuilt mine using a Hoffman kit in order to get rid of all the PCB stuff. The amp is killer but the pre-amp section gets loud at 3 and with humbuckers there doesn't seem to be enough highs. Thanks for posting this video.

The link to the schematic not found the file. Could you repost the file please? I want to build a SE EL34 combo. Thank you in advance!

Wow...., first of all..., great video...., first thing i ve noticed was that this mic responds well to a guitar with new strings, hats off to that! second.... I would love to hear the origial take unprosessed, and hear what some EQ and compression will do to the sound....and last but not least... 7 years on....your thoughts about this mic!

Can you add the reverb with an amp that has the tremolo circuit? I want to build a champ and mod it, and id like to have both. I don't know if the reverb could sound any good into an 8 inch speaker but id love to know, amazing video

stunning vocals

Great vid. Will really help first time builders.

dude, where did you hunt down this schematic at. I want it.

did you ever listen to any I Mother Earth? I think you would really like their album Scenery & Fish if you have not heard it, based on your style of guitar playing.. nice job on the bazzFuss, sounds like you got a pretty good tone out of it!

The short tank is what I've come to know as an 'ambient tank,' made to give usually a cheap amp some depth. edit: I just discovered the MOD short reverb is the alternative for the Accutronics reverb that is the replacement for the Vox Pathfinder 15r's single-spring 'Verb.

i'm in the process of converting this into a 4-channel head. i'll be using some relays and will have clean,vox,marshall,slo channels. front panel is perfect for this each channel has pre,master,treble,middle,bass

Just saw this - Really informative! I've had a BM-10 chassis only for 30 years. Used as a tube amp learning platform. Put in the bias pot and precision 1 ohm resistors to measure current back then. Thanks very much for the insights. I grabbed mine form of the attic and ready to dig in.

I built a 15W Liverpool several years ago and have a 2W version in the works now. It's a wild circuit. I love your take of "playing the amp as much as the guitar". You're absolutely right on that one.

What is the max qty of effects per patch?

Thought you were going to show us what you did to get the grittyness back.

Great job!!

Appreciate mate. Helpful to me as i have one.

So where do the Master Volume JMP (76-80) 2200's fit in to all this? Are they Plexi cascaded gain master volume amps?

mistake you have to use exactly the same recording not many takes .

I did every mod here except for the pentode triode, cause I didn’t find good enough directions to feel competent doing that one. I don’t feel like I have quite as much gain as shown at the end of the video. Maybe the pent/tri mod helps, but I’m a little disappointed and wanting more. Wish I knew what else to do.

Correct me, Coupling cap is used to block dc and allows ac through, what is the effect of the changing of its value?

For your cakepan deluxe; what is your rectifier choice ?

A slight bit of a fuzzy edge with V1 out.

And the Soldano is a JCM800 with higher gain structure on both series tubes along with the gain stage being higher. I’ve modified JCM800 amps for some metal players to a very close level of the Soldano.

Hi, Kley! Awesome video, even some 7 years later! Thanks for the schematic -- do you happen to have a diagram? I'd love to see the connections so I can experiment with the TMB in my 5e3. Thanks!!

I had that same whistling kind of sound and it turned out to be the cable so I chucked the cable and used a different one, problem fixed.

Aloha Kley Moving master volume to the 6V6 grid will cause coincidental bias variation on the output tube. Self leak grid bias should not be variable once set.

Aloha Kley, The 5F1 inputs are a bit more complicated than described. For single jack input, #1 is normal for a guitar. #2 is -6dB (25%) for dynamic microphones etc. However, there no level shift when both are used, they are both at normal level… the normally closed contacts on the jacks reconfigure the input resistance to make that happen.

Look at baby bear!, I have an ISP theta preamp pedal, the red one, you can play death metal on a kazoo with that one, if you dial in the eq solid., and I just recently got an Ibanez pentatone preamp., I’ve heard people complain about the tone of that one, but it’s them, not the pedal, plain and simple, that one destroys planets all day long, single coils or hum buckers., also both have a great noise gate.

Ok…. We might be dorks…. But this video was….DEEEEE..LICIOUS … You didn't even mention “which way do DC electrons flow”… it kind of doesn’t matter .. But the most fun part was Not even a big deal to you…. Just drawing the signal path from the input jack out through the split at the inverter and then out to the output trans….. I recvd two years of electronics training in High School vo-tech….. so long ago…. We used slide rules… And I was SEARCHING FOR THIS VIDEO…. I had most of the concepts but they were covered 50 years of silt. So …I WILL smash the subscribe…just as my sincere thank you. I have a Twin Reverb… because I can’t afford a Princeton… 1976 with the master volume… If “ everybody hates the MASTER VOLUME”…on those Fender amps….Does just turning the MV to ten “ fix the tone suck”?… or how do you mod to bypass that portion of the circuit? Also in the mid 90s ( functionally PRE internet) in an antique store… I bought a 1950s Gretsch amp… it does power on and play… but 1) the trem only responds with one pulse..and then goes steady… I’m guessing that a cap is charging up… but then…??? 2) because of its age… I am afraid that a cap is going to fail and short…and then smoke the amp… so… A) is this a reasonable concern B) is recapping the whole power supply wise or unwise C) I hate the idea of modding an all original amp… but smoking the amp would be worse. Thank you for the inputs…

_// Thanks for sharing the video! Let me tell you something important: God loves you! God loves us ! He is no respecter of persons! because God wants us all to be saved! and let's go to the knowledge of the “Truth” God wants to save us from eternal damnation, which we all deserve because of sin, who entered the world through Adam, and death entered through sin, and thus death passed to all human beings, Therefore, we are all “Sinners” But God's Love was so great for us, that he sent his only Son (Jesus Christ), gave him to this world, to die and rise for all of us! No Respect of Persons! so that everyone who believes in Jesus Christ does not go to eternal punishment, but rather has “Eternal Life!” “ Jesus Christ died for our sins, according to the Scriptures; and he was buried, and rose again on the third day, according to the Scriptures Jesus Christ came to call sinners to “Repentance! “ and, he who believes in Him, has “Eternal Life! “But whoever refuses to believe in Jesus Christ, the wrath of God remains on him. Then, as through Adam's transgression, condemnation came to all human beings, in the same way, through the justice of Jesus Christ, justification of life came to all human beings! All of us who believe in The Only Savior of the world! The Only Mediator between God and us! The Lord Jesus Christ! The son of God! All of us who trust in Him; we have “Eternal Life! “ And we must know that there is salvation in no one else; because there is no other name under heaven, given to human beings, in which we can be saved. Only by Believing/Trusting in “Jesus Christ” can we be Saved! But Jesus Christ also said: Not everyone who says to me, Lord, Lord, will enter the kingdom of heaven, but he who does the will of my Father who is in heaven. Therefore, we must be doers of the Word of God! and not only listeners and/or readers, deceiving ourselves. So let's read the Word of God! There is His Will! what God wants us to do! Let us read mainly the Gospels; Matthew, Mark, Luke, and John, and let us pray to God, our Heavenly Father, all the days of the life that He gave us! God loves you! God loves us! To Him alone be the Glory Forever! Amen!

The AX8 is a monster modeller !

Doesn't match the Reaper download, and it didn't work.

Why do you do that thing with your mouth while playing?

Dear Mr DeJong. When you went to cover the preamp, why did you trace the HI input to the top of the 3 pin terminal (Header 1 to Header 10)? I own one of these Monoprice15 watters, and all I have is a single instrument input. Can't wait for the speaker to be broken in. Good for the price, it doesn't have an overdrive. It has an adjustable distortion. I have yet to open it up. I will have to see if there's a set of diodes shunt to ground or if it really uses the preamp circuit to push the amp stage. It's funny , I have a little 8 watt solid-state HiWatt someone gave me and it's "overdrive" is a pair of diodes to ground from the 4558 opamp and not in its feedback loop all before the output transistor, hence it's hard clipping or distortion. On the Monoprice, it's sort of nice having it dialable, but I would rather it being switchable and preset the overdrive, er,...distortion.

The music is really good in this review.

Just add an graphic eq pedal in front or in the effects send and you've got most any tone you like- no need to swap out the speaker. I did swap the 3 12AX7's for 3 lower gain 5750s, much happier with a tamed overdrive. czcams.com/users/neilslade

why not make both channels sound better and more usable? in v2 i recommend an rca or a ge for an american tone and at v1 you can have a mullard i63 which will sound more like a bassman great for drive and single coils. enjoy!

Hi, do you have any insights to share with regards to what you've learned with the thru hole sizes for various components? Thanks

Hi Kley, great video! I have a question: At the collector there's going to be a DC biasing voltage (of around +3.3V assuming the transistor BETA to be 100 if l did the maths right), so that the amplified signal has headroom and not clip just yet. But then the signal will be almost completely positive in voltage. Is the decoupling capacitor going to literally subtract this 3.3V from the signal or something like that? I get the feeling that the diodes are going to absolutely crush the signal otherwise.

did you connected the gain knob without any eletronic component? direct in the out board and out jack?

hi dear, is there possible to preamplifier a dynamic mic ou a guitar adapting a plug or respective cable? if yes, can wee add tube distortion?

Thanks for posting. I will be experimenting with mine. Just a thought, instead of removing the surface mount components, you could cut the track. That way you could put the circuit back to normal by simply rejoining the track with a bit of wire. Also it would have been good to hear the comparison between the speakers. Great video, thanks.

No BS, just a demo. Thanks! I needed an example of how much proper shielding could reduce noise and you did it!
