Who to trust when buying vintage ss ?

@soix

I agree, Schitt is a good idea. Do they do integrated?

I think I will suggest vintage NAD integrated  in the end.

@tonydennison No. AB.  Pure Class A runs HOT. You don't need or want that. Especially at this low price point. 

Are these Class A?

Yes! Look at Ragnarok Integrated Amp $1499 Power Output, Speaker Outputs:
8 Ohms: 60W RMS per channel
4 Ohms: 100W RMS per channel

@ditusa If he would go that high, I would tell him to buy Quicksilver.
