Hello!
I`m trying to troubleshoot my 1176 (built on a PCB from Gustav). The problem is that it doesn`t compress, and the levels are varying every time it`s powered up. I`m tring to learn how to use my scope, and I`m feeding a 1k sine to the input. I get a sine also on the output, but as I said the level vary from time to time its powered up. I`ve disconnected the OEP output iron just to rule that out (it did make the signal about half in power from before the transformer, but that`s varying with the "normal" signal strength so I guess that`s fair enough).
Should I read a clear sine at the attack pot? I read a fine sine on the rest of the pots though. It seems like there`s something happening around the 333-diodes... anyone who maybe has a hint for me?
Thanks
