The amp itself seems ok when the tremolo/chorus switch is off.
When the chours is switched on it works and sounds quite ok BUT only on the right speaker (if looking from the front direction of the amp) and the chorus sweepes with a "SWOOOSSCCHH" sound.
Regards Mikael Hi again ENZO As you mentioned the IC MN3002 I just wanted to mention that yesterday when I was dealing with the PCBs I found that the the two small electrolythic caps around the MN3002 produced a lot of noise/hum when I touched the top of the alu shell. Is this just a conincidence or an indication that the fault could be the MN3002 or perhaps the caps?it cuold be a bad MN3002, a transistor or two, a small component, etc. Regarding my electronic skills I know perhaps more than I expressed...I have built some guitar effects and I know the difference between resistors, IC:s, transistors etc and I have and can use a multimeter.I am not that skilled in electronics so even if I found some schematics (and there are several versions.. You will need to know how to identify the parts, take voltage readings, and even use an oscilloscope to look for waveforms, not to mention remove and replace solderded in components.Plus you would likely need to find sources for your parts.
