I pulled one out and looked , the best ones to put back in are the 10 amp / 400V PIV diodes. Radio Shack sells them.

its got to be more than 10 amps .its got to make power for a 100+ watt amp.ive heard old radio7
around louisville up grades the power supply section to around 30-35amps.this is what im wanting to do as well to this 2990 power supply.
ive got the 2n3771 transisters and up graded the
voltage regulators in the radio and the power supply,added 2 more caps of the same value as the originals,just need a up grade on the bridge rectifier around 35amps or so?

10 X 4 = 40 , 16.8 V X 40 Amps = 672 Watts / 40% EFF = 250 Watts.
