Crikey, 9 years ago! Yes, I sorted it, but can't remember if I found a diagram. If I did it will be in a folder somewhere.
I don't remember alot about it, other than I think it had 'special' part numbered transistors and those curious oxide-coated heatsinks that don't need an insulating washer in order to keep insulated. |

I have one where both channels are working but on the parametric pots the -20-+20 feeds back when it’s turned above a 1/3 of the way up I’ve cleaned the pot still the same any ideas thanks mark

if its an active filter circuit it wont be feeding back I dont suppose, it's probably bursting into oscillation. I'd have thought it was a pretty simple circuit, maybe based around an op-amp. Make doubly-sure the pot is ok and properly soldered before getting into the electronics, or it might have a dead spot.
