VTL stereo 90/90, resistor value

[audiomatic]

Hi,

I have a VTL stereo 90/90 amp on my workbench with a dead right channel. As the faulty amp ran unattended for a longer time, it seems a lot of current has been flowing and there are two resistors on the PSU Board which are totally burned. The resistors are unique (i can't check the other channel for values). I have two different versions of Manley's VTL tube amp book, but they do not give any information about this special PSU. I already contacted VTL but they do not reply. Anyone can help - any owners of stereo 90/90 amp perhaps?

Kind regards, Michael

Yeah not much info as far as schematics go. Are the resistors in the high voltage section or part of the bias supply? It might be worth trying to sketch out the pcb to see where they are in the circuit.

They look like two resistors to make an artificiel centre to ground the heater circuit.
It looks more like there is a short on the circuit board and the resistors are overheated by that and are ok.
