BTW my latest iteration above, mounted on a proper heat sink is thermally well behaved. Driver bias goes quickly to 9.5mA, then over several seconds to about 11mA. Over the next few minutes it hits a maximum of about 12mA, then settles over the next few minutes back to about 11mA where it stays. DC offset changes a maximum of +/- 15mA, and settles within +/- 10mA. All quite acceptable.

Next is channel two, then plug it into the main system for a listen. Will probably take me a few weeks, between other things.

Thanks Sheldon

You see, SSA beast can be thermally tamed, now it's like a pat.

DC offset is OK, no need for servo at all.

Just take it slowly, in that way you have firm control, plus no stress.

Thank you Igor.

Four hours of listening the upper setup showed the SSA amp can drive low efficiency/low impedance speakers effortlessly. Very transparent, high resolution, full harmonic presentation from 12" black discs.

It was a big pleasure making SSA BIGBT HP, learning process all the way, meeting new friends on the forum and continuing to develop new amps in TSSA thread.

Some pics from today's assembly and later music session in a system consisting of Clearaudio Ovation, MC Cartridge Stradivari V2, Nano Phono Preamp, Absoluta Talia stereo preamplifier, Magico V3 speakers, Ktema speakers.

Yes, all the way analog chain was the best performer in given system. Vinyl with analog recording material still holds the magic in music reproduction.

We were enjoying all the session and it was, as usual, unawarely over too quick.

Somehow analogue most often sounds like music and can give a lot more emotional fulfilment than can processed digital signal . The technical argument that digital source is more accurate does not hold water for me as it all too often cannot reproduce that magic which analogue so often does produce! This differential, for me at least, makes me very suspicious that the present state of art measuring instruments are usually measuring the wrong parameters.

Well done!!

I heard very good digital master tapes but somehow it does does make it on a medium we can access. Refference Recordings sells copies of their mastertapes but then we are stuck with classical and maybe not the best preformance.
