Better check there is no power going to the big Tx first. There is
little current surge at power on , so suggestive of no main Tx coming
on, just the little standby Tx.

Does injecting audion to a direct-input (€œ6-ch direct input€�) get you any
output? This bypasses the preamps.


I'll try that tomorrow as well as checking for mains on the big Tx and
then a drive voltage over the D912 back emf preventer to the relay,
which is about all that is observable without taking the amp apart.
Amazing that there would seem to be 2 fuses buried at the rear , behind
the relay, cannot even see any part of them. Perhaps some traces are
probable to check those fuses without dismantling
