The problem with this amp is that when you turn on the transformer makes a loud buzz. When i isolate from amp the transformer goes quiet. I have just got schematic from Enzo. So ill work through all the components.......Thanks....sean

Seantdrums, quick way round this would be to plug bulb limiter in..most common faults with avt amps are blown o/p chip stages unplug it and re-power the amp back up.

Having dealt with marshall in the uk for many years I carried out countless repair's to the valve state amps such as AVT2000 Plus AVT H amps with thermark o/p device up grade pcb.
