So to cut a long story short my ARC ref 75 has just been returned after 3 months at the service department. Diagnosis of fault DC on the input of one channel - busted FETs.

I've hooked it up but not switched on yet. I measured for DC at the outputs of the Truth pre. With the multimeter set at 200mv I get 0.02 on both channels. Please can someone tell me if this is ok? It seems very very little but I'm so paranoid and dont want another 3 month absence and 900€ bill.
