Power Amplifiers

Carver M500t.

IN 1995 I PURCHASED AN AUDIO RESEARCH D-400 MK 2 THAT WAS A STORE DEMO.
I HAVE PLAYED IT ALMOST EVEY DAY SINCE THEN. IT HAS NEVER BEEN SERVICED OR REPAIRED. I USE IT WITH AN ARC REFRENCE 3 S.E. PRE AMP THAT JUST GOT NEW TUBES. THE AMP IS SWEET AND MUSICAL, AND HAS PLENTY OF POWER. BEEN THINKING OF GETTING A NEW REF. 160S AMPLIFIER BUT CANT SEEM TO LET THE OLD ONE GO. IT'S BEEN A REAL PLEASURE OWING IT.

A 2000 Mark Levinson 383, now with New capacitors and service. It Will be with me for the next 15 years too.

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.
