All I hear from Oinkerton is "Oink....oink oink oink......squeal, oink...."

I doubt he makes any thing.

I am now doing 845 amps, two per channel for 50 watts each.
I expect music to be real fine. Damping factor good, noise low,
bandwidth wide, distortions negligible and maybe I can add 6db of global NFB but
I doubt any difference due to some **added** NFB will be heard.

Depends on the speakers, the reduced output impedance may be useful.

You probably won't need the NFB. The biggest problem with 845 is not
deciding how much NFB to use but steeling yourself to let them out of
the door. 845 are God's own tube. I really hesitated when I needed the
space, wondering if I shouldn't keep the simple SET 845 rather than my
Millennium's End SV572-xx amps.

It's an excellent tube, as tubes go, but of course we've had seventy
years of progress since then.......

Trev has never done anything like this and simply doesn't understand.

It's not so difficult to open your mind to new experiences and new
ideas. But first one has to stop being a smartarse, and that I don't
think poor old Trevor can manage.

You of course would be the master of this art - except that your arse
is the smartest part of you.

With 845, just no need for the 106dB of added NFB used in SS amps.
I don't care a bit about what Trev says.

With SS, no need for the massive cost of the output transformer for 50
watts of single-ended tube amplification, plus of course you get much
better linearity than even the mighty 845 can manage. A really good
60-watt SS amp is very easy to implement these days - and you can buy
one for the cost of a pair of those OPTs...............
