Right channel dead on AR VSI 75


The right channel of my AR VSI has no sound.  I’ve swapped speaker cables with same result.  Left channel is fine.  Right channel dead.  Same result after swapping tubes.   Any recommendations?  Thanks in advance.

Dead tube took out resistor in the bias circuit when it crashed? Happens all the time with ARC amps which have no protection in the circuit (and they are not the only manufacturer that does this).
