This is gold to me - merci ! I need to have a look at mine since it's NOT working perfectly - i'm not a pro at tube/audio electronics - your video is giving me some precious background i lack. Hi from Montreal !
I would love to do some work on a Binson, but sadly there are none around here. Also would love to see the Dynacord stereo echo, also rare as hen's teeth!
Are these pretty much the same as the Klemp Echolette NG51? I recently got one(No telefunken tubes unfortunately) need to service or find someone. It looks to be beyond my skills. I actually got it for that overdrive sound. Wicked! But I love me some delay probably even more. Wow….I guess it has ‘more’! That looks beautiful!
The machines look similar but are not the same and were made in different factories and have different schematics. More info gleaned from comparing schematics.
@@telefunkian thanks 🙏. I will look into that. Do you service the NG51’s or is it too much to take on? I’m in Mt. and I’m not sure there’s anyone locally who would, could or should take this kind of service on.
I don' t normally take on projects for $, just for the love of it, and I am not terribly well versed in NG51s, the Dynacord was a bit of an outlier for me. There is a vintage Echo group or two on FB, you may find someone who is the US (MT=Montana?) who is more expert than I am. I am just a lowly enthusiast, not a pro technician. If you really can't find anyone else, you would have to get the machine to me here in Vancouver. First thing I would do if your machine is not working, and assuming it is turning on, is check the resistances of the heads and see if they are open circuit or shorted, and if so shop for new/old heads, that will be the rate limiting step in getting your machine fixed if they are blown. On a Dynacord, the recording heads should be ~450 Ohm DC resistance, playback heads ~1000 Ohm. Near zero or infinity (more likely) is blown.@@GIBKEL
@@telefunkian you could have fooled me. I thought you did an excellent job running down how to service these. I am even more “lowly” but luckily I know that it’s above my pay grade. Currently working on an old Magnavox console from the early 60’s with excellent schematic and straightforward parts list/voltages. Paint by numbers comparatively. You exhibited excellent skills. I’m only sorry that you didn’t have a demo. Maybe I missed it. I can only imagine that this could be used in a number of ways-instruments or as studio tool. Wonderful video.-thanks for tips!
I haven't finished the series of videos I began filming on this beast as I opened the can of worms of designing a variable speed controller for the three phase AC motor. Basically a variable low frequency sine wave generator coupled to a D-class amplifier to drive the motor. Prototypes work but stuck at the stage of miniaturizing it all to fit in the Dynacord chassis and got stuck on ~revision 3 of the design. So right now the Dynacord is disassembled into two boxes and taking up the corner of my studio.... sigh....@@GIBKEL
What a beautiful machine, very elegantly put together. German electronics from the 1940s - 1960s are a pleasure to work on, because you know they will be a delight to use. Where did you get the mains connector for it? Those are impossible to find.
The mains connector came with the device, as it was in use in a studio in New York for many years prior to my purchase. They are not as rare as you might imagine as they appear on eBay from time to time (search Echocord or Echolette, or 'kettle plug'). Thanks for your comment and thanks for watching, more videos to come!
@@telefunkian You are right, I found one on eBay, for 11 dollars (!!!). I occasionally sell a couple when someone finds my video about Uher 22, but I sell them for 3 euros. Speaking of eBay - I don't know if it is a temporary thing or the world has gone absolutely mad, but eBay prices are off the charts, just insane. I'd like to buy a Micromoog one day, but on eBay there is a totally busted one from Germany and the seller wants 1000 euros for it. Just completely crazy. Other older musical instruments - same thing, and often they are not even rare or super-desirable. I guess I'll be building my own everything out of junk parts found at the side of the road at this rate.
@@I967 Part of the genesis of my channel, I made a 'deal' with myself that I would only buy gear if it was broken and I was going to fix it myself, or if in the case of modules etc. I built them from scratch. Now I spend all my time editing videos and not enough time making music!
@@telefunkian How nice! I buy mostly broken stuff, too! I've got a room full of faulty equipment waiting its turn to be made alive once again. You have an interesting channel, well done!
HI this is an excellent video but I thought the Super 61, 62, 64 came out in the model number years eg super 61 in 1961 etc. I have seen a schematic for the Super 62 dated 29 January 1962.
Val you might be right about that, for some reason I had it in my notes that the 62 came out in both 62 and 64, but changed it to 62 in my narrative. I'll try to dig into this and will correct it in the description when I can find out definitively. Thanks for watching and for the feedback, more videos on this to come.
@@telefunkian No worries it wasn't a criticsim it does get confusing. I've been researching the old tape echos for many years and have over 150 brands and hundreds of models amongst those. It's a labour of love. It's in bookform on my PC which is now over 800 pages long. No sooner do I think I've found them all but then a new one comes up. Love this stuff. By the way I am age 75 and an old Canberra Australia muso.
@@valstarr1238 Well sir, may I humbly suggest that that book on your PC ought to see the light of day. I am but a bumbling enthusiast, sharing my journey with viewers in the hope that my videos are helpful, or entertaining, or both. This is one of the older devices I have worked on, and it is sad for me to see how much information on these things is being lost to the ages. Thanks again for watching and for your comments.
@@valstarr1238 Dear Mr tape echo lover! oh wow, 150 brands!? ...thats crazy, i would be happy to get some infos. You should bring the 800 page book with all infos to the community in the whole world.

Yes, but it is rather complicated. It involves making a sine wave generator and using it to drive a class D power amplifier that drives the AC motor. I have yet to finish the PCB to house it all but it works as an off board prototype. The motor seems to be happy running at 20 Hz, about 1/3 the normal speed, and of course at higher frequencies. The main reason for pursuing such a thing is to be able to adjust the speed on the fly, like with a Roland Space Echo, for dub type effect. Not yet satisfied though.

Amazing kit and engineering, thanks for posting
Thanks for watching!
Awesome video. Thanks for posting. Just bought a broken machine so I'll definitely check in here if I get stuck!
Thanks for watching and for the encouraging feedback.
This was great, thanks so much. Maybe some time we could see some Binson repair too. Excellent channel.

Hey man! Thats a brilliant series of videos. THANK YOU!
Thanks for watching Torben, glad you like them!

Greetings from Austria
Have you found a way to change the tape speed?
Yes, but it is rather complicated. It involves making a sine wave generator and using it to drive a class D power amplifier that drives the AC motor. I have yet to finish the PCB to house it all but it works as an off board prototype. The motor seems to be happy running at 20 Hz, about 1/3 the normal speed, and of course at higher frequencies. The main reason for pursuing such a thing is to be able to adjust the speed on the fly, like with a Roland Space Echo, for dub type effect. Not yet satisfied though.
All of the above is powered from the motors transformer winding.
@@telefunkian When you finish it I would buy it immediately 😉
