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
Thanks for schematic, i repair a lot of Marshall AVT 275/150 amps main probs the TDA's. Ive followed a lot of your posts on peavey repairs of various amps....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.
