I just purchased a Lincoln L24 integrated amplifier at an estate sale for $5. It appears to be in pretty good condition, but probably hasn't been operated in quite a while. It has nine tubes: (4) 6EU7s, (4) 6BQ5s, and (1) 6CA4. There are 2 canned multi-capacitors on the top side of the amp. One is a combo of 40 uF 400V, 30 uF 350V, 10 uF 300V, and 50 uF 25V. The second is a combo of (2) 10 uF 350V capacitors.
I am wondering how I should proceed with testing the amp out. I have a variac, but I read somewhere that the rectifier tube will not start passing voltage to the capacitors until it has reached some minimum voltage. Should I replace the multi-capacitors before supplying voltage to the amp? I think my options for replacing the multi-capacitors is to find a way to use individual caps instead, or "restuff" the cans myself, or send them off to be restuffed.
I would appreciate any advice on the best path to proceed, and also any information or experience that someone may have regarding this particular amplifier.
