I've ordered motor run caps, not quite sure how I missed the state of mine!, no fool etc.

I'm using service manual scan (0484 10th Edition), I presume 0484 means April 1984, page 24 describes the operation of the old speed control board with the inductor, page 41 has a description of how the later IC board works and at page 73 (according to my pdf reader) is the circuit followed by the parts list of the IC board, can anybody tell me if this is the latest version of the service manual?

I have come up with an improved way of slowing the 21v supply build up, I'll publish when I've tested it out.

Another question, has anybody modded their A77 as suggested by Angus McKenzies article?
