Hello there,
I am new to this forum and have been into valve hi fi gear for about two years now and am eager to learn how to build my own valve gear.
Currently I have two Sound Reference monos each running 4xWinged C KT88's and two 6922's, great clean massive sound running into Sound Reference Pre(tube) with phono stage, Vandersteen 2c's and a Rega Planar3 with RB600 tonearm and Ortofon 2M Bronze stylus.
I love the sound I am getting from those KT's!
I have recently been reading up on the Soviet GU50 copied from the LS50. I am intrigued by these tubes and was wondering if anyone out there has schematics and transformer specs for something single ended? There is little on the net and I would love to build something out of this wonderful bizarre tube.
Thankyou in advance.

HI! In Russian Internet are very many information about schematics and transformer specs for GU-50, but in russian language
I have found about transformer: I max = 120 mA, Ra/Rn = 3.5 k\4-8 Om (6.3 optimal), transformation factor 26:1, 20 Hz-25000 kHz
Schematics: http://klimanski.com/wp-content/uploads/2009/10/gu_50_9.gif
Still write that power output is more than 5 W it is not necessary to do - if Your want very good sound.

It I do not know. I do not design valve amplifiers, only on semiconductors. Here, for example: http://www.diyaudio.com/forums/chip-amps/79303-chip-amp-photo-gallery-141.html#post2161415

Suburb? I'm at Camp Hill.....S/side.......mainly solid state I'm afriad but the redeeming feature is that they do run in class A and I at least have the tubes to build a RIAA pre-amp eventuallllllllllllllllllllllllly!!!!! Ha ha.
Welcom aboard. There was a speaker builders thread for the Brisbane area active a year or two ago. They met several times.
If you want local contact you might modify your personal deatils so the locals know Qld...Great South East etc.....on the otherhand I CAN understand the desire for a quiet life. And today we can all say "Go the Cane Toads!" or words to that effect.
