Echocord S65 tubes tape delay needs repair

[guydanieli]

I am looking for a technician who can repair my Echocord S65. The amplifier works great, but I have no echo.

Thank you!!

is the tape loop intact?

Yes, tape is new! I even tried it on my other Echocord, Tubes are new. I have a little bit of distortion. It can be capacitor. I contacted a Belgian man (Retired. He is 93) and he worked a lot on those units. He told me to replace capacitors at first!

Thanks a lot!

I have echo, but weak!

have the heads been demagnetized recently?
check the bias at the erase and record heads and whether the bias oscillator is working properly.
after that check the supply lines and start replacing caps.

If you have distortion at playback, the bias oscillator has failed.

These apparatus of the sixties might be packed with brown resin dipped Wima caps. These are well known for failing over the decades, especially coupling caps are getting leaky thus deteriorate the bias of the tubes. I repaired some Grundig tape recorders of that time with exact that problem. They worked after replacing all coupling capacitors.
