I bought mine new in 1976. I got the 210r rack mounted model. The potentiometers got pretty scratchy after about 4 or 5 years. And after 40 years I had to recap the unit.

Oh I remember also in the early 1980s I had to replace the sockets for the ICS because they use those really crappy CA sockets that developed a four connection. The symptom was that the equalizer began oscillating like this one is.

I have a Soundcraftsmen EQ that also used the 4136 chip. It's basically a quad 741. It's an inferior sounding low-fi chip. That EQ used only one per ch. So I replaced them with LM837's using a DYI adapter (daughter) board.

Do you take new projects? I have a Spectro Acoustics 210 in working condition…no obvious distortion…but I’d like to get it “recapped” and with new sockets as you did on this one. At the least, can I get a list of the parts you purchased and replaced?

Hi, I can send you the parts list, please contact me direct by email, link is in the about this channel section. Appreciate the opertunity to service your EQ but I have a number of projects lined up so am not taking on additional work at the moment.

Hey Eric, you mentioned you would help me on a parts replacement list….but I found no way to email you in the “About” section. I replied to your comment in my previous post. Check it out, please. I hope you can help me. If I try to repair mine it would be my first repair. Mine in in working condition with no known problems buy after 50 years its time to recap the while unit as you did. Thanks!
