This amp's tremolo is thumping so hard it's more like a knocking sound. Anyway I'm using the schematic to the royal guardsman, it appears to have an identical tremolo circuit. So far I changed out the oscillator caps C216, C217 and C218 which did nothing. Might put those back after when I'm done. There's 23v on R234 and about 16vdc fluctuating on the collector of Q206. Not getting much of a reading on the emitter.
The 'MOD BAL' R230 doesn't seem to be doing anything.
Does anyone have an idea what could be causing this?
Thanks
