I'm, stripping my dads QED P300 to get my head around building amps , it pops and crackles like my ex wife but its a nice sound when its in perfect running order.. so I was wondering if by a" very long shot" anyone happens to have a service manual for it..? I have already emailed QED but incase they cant help me.. I have traweled the net like a Icelandic Cod fisherman .. no luck so far.. heres hopeing
It is an old amp and first, u have to solder the pcb for solving most of the problems. If it crackles on turning any of the controls, then u have to lubricate or replace that control potentiometer.

Yep its an old amp 🙂 Its has a power on /off switch that is all..
An externally hosted image should be here but it was not working when we last tested it.
I have already started to document and order the parts
