Hi,
Irrational as it might be, I´ve become interested in Circlotron amps lately. I have a big stash (40+) of 6S19 tubes, 20 noval sockets and some interesting power transformers (two 2x6V 50VA toroids for the heaters and four 68V 100VA EI transformers for the floating output stage rails).
Some questions:
Can an OTL circlotron output stage operate in class AB?
Would 95V rails be waaaaayyy to low (using 8 x 6S19 per channel*)?
Is a tube or a solder joint goes south, would it mean the end for my speakers?
* With 4x6S19/rail, ie 8/channel I should get a peak current capacity of about 1,2A which should give almost 6Wrms @ 8R.
