Hi.
I have had a burndown in my VTL 90/90 power amp. One of the 6550s got filled with smoke and the glass broke. On inspection of the inside I found that the power supply (left side) had completely burnt up. The big rectifier was only a lump of melted metal. The power supply printboard is destroyed. The big capacitors seems to have survived, but I believe there are components on the main print that is destroyed as well.
Does anyone have a circuit diagram for this amp? I must try to resque it from its horrible misére.

Regards trondkj

You may want to check the resistances of the power supply transformer and the output transformers. Check for open windings or shorts as well.

I think I would do that before finding a circuit diagram.

I will do, of course :)

i have a vtl 90/90 deluxe amp when u want i can post a picture of the inside
for help also mail to vtl.com they helpt me in some questions

Oh man that's a major shame as those are very nice amps.
