Problem with Rocktron R120C

[joecool85]

Well guys, I checked the ICs and now the amp is working fine and I've played it several days through both the high and low inputs on the gain channel and the issue seems to have gone away. It's puzzling, but I may eventually solder in sockets and try different ICs in place of the current ones. Thanks again for all the help!

Did you check or change the ICs?

I checked all the ICs using compressed air. I haven't tried changing any of them yet.

I checked all the ICs using compressed air.

That does create a rather mind-boggling image of inflating IC's...


{movin' right along however}

I'd say there was a fair chance you have something like a dry joint or crack in a PCB trace somewhere, and that your attention has "fixed" it for the moment, but I would be prepared for it to return.

Fitting IC sockets seems like a good idea ... until you start struggling with the bad connections they so frequently cause.  By all means fit them while you are auditioning different IC's, but once you have found what you want you would be well advised to remove the sockets and solder your chosen IC's directly in.
