The chorus unit just came back on again. This time I will quit while I'm ahead  :tu:

At least for couple weeks or so, until I get motivated to hunt for cold solder joints as you suggested.

Now if I can get rid of the OOPS cleaner smell . I'm sorry I used that nasty stuff to clean the gunk that accumulated under the plastic screen on top of the head.  When the amp heats up, I  still get the chemical taste on the back of my tongue. I the amp outside yesterday to air it out, but that hasn't helped much. Maybe the cold air helped to jump start the chorus unit........no clue.

Thanks again for you help!

Greetings from Colorado and thanks for offering a place to discuss SS amps.

I picked up a Peavey Stereo Chorus 212 amp a month ago, along with the footswitch. It's a 1990 and the version 1, I think.

Problem:
The chorus unit was not working when I bought it from a pawn shop, so I got a good price...$100. I planned to take apart for a thorough cleaning a week ago, and the chorus unit mysteriously came on and worked fine BEFORE taking it apart. I cleaned the amp anyway, put it back together and everything sounded fine, EXCEPT the chorus unit doesn't work again! I took it apart again, jiggled some wires and still nothing.

Any suggestions? I don't have a background in electronics, so please go easy on me. 

Thanks,

JD
