Hi,
I discovered that the IC on the compressor circuit, the one that in the schematic is called 3080, give some problem. removing it the amp sound perfect with it sound really bad. looking at the IC looks like another "3080" with the pin out that don't fit with schematics ... have someone substituted it sometimes?

The 3080 is not like any other IC in the amp. You cannot put other ICs in place of the 3080.

I know, I had a CA3080 installed but sound really bad even when the compressor is not activated... I get a distorted sound on some transient.
