I have 845AA (Integrated) circuit in electronic format but only hard copy version of 845C mono. They are virtually identical but I can look for the 845C and have it scanned if you wish. In the meantime I will email 845AA.

HT is approx 1,000V but measures about 1,050V here in Oz where mains is 240V against the 230V primary tap of the amp.

I can't remember the details of the OP traffo but I think the primary was around 5K. The early monos had potted trannies which were ordinary but the later integrated amps had conventional EI lam trannies that sounded quite good. I'm not sure whether they changed from the potted units in the monos.

Hope this helps.

Rgds,
Naz
