Pioneer tx-8100 restoration

I'm in the process of restoring a tx-8100 tuner to go with my sa-8100 amp. I have the below cap/transistor list from the service manual. Any tips for suitable replacements (particularly regarding transistors)?

I've read the posts on here regarding this tuner, which will definitely be useful in getting it going - I've not seen a complete parts list, so hopefully this thread can help some others too!

Here goes:

If anyone has the service manual, is there anything I've missed? (I haven't included ceramic caps if that makes any difference)
Thanks for any and all help!

anyone have any info on this tuner?

Not the 8100. I have the tx-9100 that needs rebuilding. You are probably going to have to get your tuner re-aligned if you change the caps on the tuner board.

I have one to rebuild so I'll watch this very carefully. Please let us know where the road bumps are.

Mark,
Thank you for that list.

If I replace all these components, particularly the ones on the tuner board, will I need to re-align the tuner?

yes, but it will be serviceable until then. I think this one avoids anything major - I MIGHT have to talk you through a minor stereo decoder 76khz setting. manually following directions, you should be able to hit it pretty accurately.

of course to get it to full spec - the alignment will be needed - things like separation, some distortion etc,...
