My main amps are based on a pair of Altec 1569A monoblocks. The peerless transformers remain, it was totally gutted and expanded into a 125w. voltage regulated (not ultralinear, triode or pentode type) amp with low global feedback and twin 3" X 7" electrolytic storage caps.
My other audio system has a Dynaco ST70 but with new huge storage cap, terminals, RCAs, SS rectification (kept the 5AR4 tube for slow start-up) and is transformer tapped to voltage regulated type use. It has outlandishly stunning bass compared to a stock unit and reduced global feedback. Both systems use SR blue fuses.
My two video systems (75" Sony 900 series) use 1978 Yamaha CR-620 receivers.
I have a space EAR 890 as backup but it's not in the same class as my main amps but is a very similar sounding amp to my Dynaco ST70.
