Yamaha C-70 Project

Its not going to be a quick deoxit/caps job

Ha! There's about 17 million caps in this one, definitely not a quick job, since you mentioned
Best of luck with the restoration, mine was quite a ride, but totally worth it!

Got a C-70 that's been waiting maybe 18months, opened it up yesterday, still on the bench "untouched", a little bit of
glue damage... can't seem to muster the courage, might finish others and come back to it in 2-3months, a little daunting...

This is my C70 list from a couple years ago. May have made some changes, and I'd double check against what's in your preamp, but this is a good start.
