OK- I found one of these out of Luxembourg for (relative) sparrow-feed, listed as 'not working' that I snagged the other day. Although it has not yet arrived I am preparing for the restoration. Some history:
This will be my second A722. The first is now residing happily (and heavily) used with my 13 YO grand-daughter paired with the A720 and Piccolo speakers. That one was 'working' when it came into my hands via Denmark, needing only a few caps, lamps and a bit of cleaning. Although compact inside, they are assembled logically and every part can be reached. The intention here is that this unit will join my other A720 in the other all-Revox system that includes the various moving parts - RtR, CD, Cassette and TT.
I have a good, clean copy of the shop manual & schematics. I have a good stock of compatible transistors and the means to match them if needed, most of the caps (I will have to acquire the correct 10,000uF @ 63V main filters (4), but I have identified good sources with quick delivery (including Amazon of all places). '
In any case, has anyone here ever dived into this amp? Any suggestions? Otherwise, I will start at one end and work my way across to the other.

Thanks in advance!
