Octave Research OR-1 pure class A amplifier. This beast was designed by Andy Rappaport, based off of his amp-1, only with a spare no expense mentality, I think it retailed for $4000 ish in the early 80s. The entire chassis is machined aluminum! Weighs in around 70 lbs, 3 internal cooling fans, those caps... Are you ready for this? 110,000 uf x 2 per channel! utterly ridiculous. Now the fun fact, it's only 42 wpc? There are conflicting numbers between 85 and 42, 4 and 8 ohm. I believe it to be 42 @ 8 ohm, it probably specs out around 80. One sweet sounding amplifier, probably won't stay in my collection, I like power way too much. But, still a fun amp to have laying around. Enjoy these pics.

But how many amps put out 42 watts of pure class A? Don't most go A-B at around five watts? (I may have this all screwed up, amps are not my forte.)

I'd REALLY like to hear it once.

In the first pic, the black amp next to the Octave. My white audio labs a100, class A to about 75-85 then AB to 100, specs out around 165 wpc.

That's a gorgeous hunk o' aluminum right there! What's you audition it on?

Yeah I saw that amp on CL for a while. Considered getting it but the drive for me was bit to far. Grats on a great amp, bet she does sound really nice.
