Hi all. I was given an early solid state Fisher 440T receiver that works but has a slight hum in both channels and a motorboating in one channel at low volume.I replaced the power supply caps and the hum dissapeared but the motorboating is still there. I've decided to give it a recap but had a question on the small electrolytics on the circuit boards. Some of the very small electrolytics have 4/35 and 1/70 on them. I'm guessing they are 4uf @ 35V and 1uf @ 70V? Would this be correct? Thanks in advance.
