Any caps that are branded CAPAR should be unconditionally replaced. The larger caps with more recognizable names should be OK.

Success! A few new caps and cleaning the grounds seems to have fixed it.
Very stable! I only did the caps on the top board as I didn't have the 10 &
100uf for the bottom board. I will pick some up tomorrow and this should be
back online. Thanks Evan for your thoughts on this thing!

Hey guys,
Picked up a nice looking Drake RV-75 vfo for my TR-7 last weekend. Hooked
it up last night and my main vfo was in the middle of the 20m band, but
when I switched on the remote vfo freq drop to around 13.9mhz and I am not
able to adjust it. I guess I got a hamfest special. Any hints on what to
look for? I have not even opened it up. Got a great deal on it however so I
hope I can fix it. I showed it to Evan, K9SQG when I ran into him there.
Thanks in advance,
Eric
