Repairing a tape echo with tubes (Dynacord Echocord Super 62a)

[burntheflags]

So, i posted this here a while back but i'm going to try again.
My echocord super is starting to sound really great with a lot
of work that i've out in to it. But i'm still having the same problem with the echo 1,2, and 3 buttons. if i press in the reverb button and 1,2 or 3 at the same time they work but not if i just press in the head button itself. the reverb button also works by itself based of the 3 pot settings on the top of the unit. i'm stumped anyone have any ideas?

Hello, I bought a s62a on ebay, and I was told that the lights and buttons, as well as the motor work well, but they couldn't check the sound.

So the thing is...it was already plugged in "at least once" a few months ago, so should I first of all plug it and check if the sound propierties "miracolously" work well?

or should I start by replacing the capacitors from the heads circuitry?
or should I change them ALL?

I went to a big electronic components shop here in Berlin and they told me they couldn't have that BIG capacitors I needed...what can I do? Any cheap/good place to buy this kind of capacitors on the internet???

a milion thanks in advance!!! : )

no one?

You might find the capacitors you need on eBay if you look around carefully. There are lots of electronics resellers in Germany and one of them might have what you are looking for..

Try here for some leads: http://www.die-wuestens.de/eindex.htm

(Ask Jan First - English Index, also in German which unfortunately I don't understand) Lots of capacitors and other parts you will need.

WRT to plugging it straight in see my earlier posts about the ballast lamp and what it can do to protect the irreplaceable components in your Dynacord.

Hello everybody,

I am almost done restoring a Dynacord Echocord Super 65, and am thankful to the information I found here, it helped me a lot.

I still have one question. I am taking out the Din connectors for all the inputs and outputs except the mic inputs, I will make cables that go from Din to XLR and Din to 1/4" Mono for those.

The main output has a switch that is disconnected when a din plug is inserted. When nothing is plugged in it, it shorts what appears to be the level pot for Instrument 1 to ground through some resistors, I imagine this is something for the use with the eminent amp where only Instrument 1's combined input /output is used, but can I just leave this unconnected and have my 1/4" output safe? I imagine so and I will find out soion enough, but if anyone has greater insight it would be much appreciated.

I have studied the schematic quite a bit, and have replaced the electrolytic capacitors, replaced 4 potentiometers (two level, two tone pots) and replaced the power receptical with a standard IEC / computer one because I didn't have a power cable with mine. If I can help anyone with questions, I will.

Should I ground the ground pin from the power connecter to the chasis? The original power connecter was 2 pin so not an issue, but is grounding the chasis a safe bet?

Also, how do the two playback heads work? When you have one head selected, and no feedback, do you get 6 repeats or 3? I get three, which has me thinging that one of the playback heads is engaged instead when set to the different speed, or mine is broken in this way, can anyone confirm?

Thanks to all and I hope to be able to help others in return.

Sorry, I wasn't thinking straight, with feedback at zero and one head selected, do you get one repeat or two? I'm wondering the implementation of the 2 playback heads.

Thanks.

Hello everybody!

I have several Dynacord and Echolette that I wish to restore (15 total)

But , I have to start with the first one. Here is the problem (The Echocord 63 works fine) Except that I only have 2 echoes (All the puch On/OFF switch work well. The machine looks almost new) And not a lot of reverb. I have a good power from the amplifier. But the Magic eye doesn't move like it shoud move. I used those echocord a lot in the 60's in Europe.
I do not know what part do I have to change to fix those problems and have a good machine.
Thanks a lot for your help.I am not an electronician, but I can change parts. I cannot tell the measurement of a defective part for example
Thank you so much!

Hi all and merry christmas time.

I am looking for the Internal wiring of the Echolette E 51 motor.

In fact I need to know how can do rewiring the internal's coils inside the motor because I need to make variable speed.

Here the ECHOLETTE E 51 MOTOR REFERENCE :

PAPST-MOTOREN KG:

KLZ 20.50-4/8-140D-B144 4922
42V - 4W - 48mF - 50Hz - 1.74

If anyone have idea how can do a variable speed of this Echolette E51 it should be welcome.

sorry, 1st post so hello to all and another echocord problem needs solving.
just got a 62a echocord.
the big problem being i only seem to get the a delayed signal from the machine. always a 0.5sec (approx) time between hitting a note and getting any sound back from amp.
the reverb control does not seem to change this. the tone control (pulled out or pushed it) also doesnt seem to do anything.
the switches all seem to work but i cant get rid of this latency.
i am outputting from the remote circuit.
the middle knob is the only one that seems to do anything. this seems to work fine (though i cant remember what it is called for now) its the duration of the echo.
anyone have any thoughts?
am i wired up correctly?
is it perhaps a problem with the reverb control?

any ideas welcome.

Thanks
