Need Complete Apt 1 Power Amp Service Manual Not Missing Pages

I've got 3 Apt 1 power amps in need of servicing and adjusting. One had some modifications done to it and has a few issues that I'm trying to resolve, and I've already replaced all original electrolytic caps, repaired some small areas here and there, and re-set the output transistors in fresh paste, among other actions. I've downloaded what appears to be the only version of a service manual online, but it is missing about 10 critical pages regarding servicing and adjusting.

One thread here was helpful in detailing bias procedures, but there is an impedance load adjustment and some other details that would be very nice to have. These are pretty nice amps, but getting harder to service due to parts long out of production.

The preamp service manual is widely available, and I even have an original printed copy, but it would be really nice to have a complete service manual that includes pages 22-25 and 36-39, if anyone can help out.

Many thanks!
 
Hi Dave,
Thank you. However, there was apparently a separate service manual for at least the amplifier. The only service manual for the amplifier I've found online is this, which is missing critical pages. You'll note that it differs from the Owner's Manual.
Somebody must have a complete copy of the service manual, it seems?
Cheers,
Greg

Looks like Unclejed613 doesn't have a profile, and I can't seem to send him a PM. Too bad the complete service manual is so elusive.
I'm working on #2 of 3 amps now, and it is a few board revisions earlier; there were a fair number of changes to the schematic and board layouts, and some different components used. The transformer is also different, as was previously stated by Unclejed613.
