You are probably just wasting your time hunting for the problem. Replace all of the paper caps, check and/or replace the resistors. As you are going through it check the work done by the previous owner, clean the switches and pots and when you get done, watch the B+ when you bring it up, 9 out of ten chances it will work. If not, then start looking for the problem.
