Power Amplifiers

I have a Adcom GFA-555 amp still in use since 1989. Great sound. Super base.

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.  

1999 Plinius SA100Mk3  Ralph Abramo of Galbo Design www.pliniusrepairs.com (pliniusaudiorepairs@gmail.com) His upgrading is transformational. 

1998 Plinius M16 pre originally owned by Gary Morrison, ultra tweaked… eventually to be upgraded per above. Call Ralph!

Since Ralph did his Deluxe Mod Upgrade on the amp there is a juicy difference which will keep this duo in my rack another 20+ yrs, when I turn 95! Dynaudio C1 Signatures never sounded so good and prior ProAc 2.5s would have loved it. What fun! Jazz Lives!

Aragon 8002 with the Aragon 24k. Great combo. Love the dual outputs.

I should have mentioned I also have the Aragon24k
i’m using PS Audio power cables for both Amp and Pre amp
