Well - I've heard a couple of such amplifiers, made by Mr.Juri Makarov. They did have more or less similar design concept: 3x6S19P @ 3.5k load, specially designed OPT, 5W, 2.1 .. 2.5 Hz to 200 kHz, about 0,5 Farad total capacitance, 2.1 .. 2.5 Hz to 200 kHz, direct coupled driver on 6S45P, 70..100 kg per monoblock. First used regulated power supply on Gu-50, and stbilised filament, the last was most simple and did use only stabilised filament.
The Designer used a special listening room with lot of natural pine wood deflectors in it. It was very quiet.
Regular loudspeakers was used there - initially top from Mirage family, discontinued probably 10 years ago, now - approximatly the top speakers from Montana brand.
Well, he is not respected by the Morons.
p.s. An important thing of this amp construction was the cooling concept. All tubes were hidden in the specialy milled radiator - to provide a good temperature stability for the tubes, and according to the words of designer - amplifier was switched off only several times a year.
Romy, looking through some suppliers I've find out Pearl coolers for 6S33S. May be it is worth to give them a try, since the high temperature consequences is an issue with 6S33S?Rerurn to Romy the Cat's Site
