The Fisher 4400 FM Receiver
#59

Yeah, the death caps. Out with them.

BTW as I told before, these devices do not require 105C caps.
PS. Unlike in the tube rectifiers, the more capacitance you have in the rectifiers in solid state, the better. I designed amps about 60 to 100 Watts.....when I could get my hands on 10,000uF for each leg, positive and negative (and those were unavailable and expensive in my former country) - I would put them in.
And if you have old Germanium diodes.....that will cut down on dissipation big time.

But....what you have is probably good the way it is.
What capacitances do they use in the power supply?
