Rotel RA06SE output offset.

Already addressed the "usual suspect i.e. the 100uf caps on the feedback side of the input long tailed pairs.
That snot it. One channel is about 5v positive, other a couple of volts negative. This is of course triggering
the DC protect to prevent speaker flames. Suspicion is on the input pairs (2 x A1016 and 2 x C2362 per channel )
PITA to get a pile of these things to gain match them.
Any other "usual suspects" I have missed?.
