WOOLCOT AMPS - Anybody heard these?

I already asked Hank about other octal based tubes, such as the 6L6 and KT88, and he said that he was uncertain that the auto bias circuit would accommodate these tubes. I have a friend who is an amp designer, who said that there was an old military Bendix tube that would work in this circuit, near identical bias and drive character, and would match the output transformer as well. He is uncertain as to if it would work without a slight circuit mod, and requires me to ship the Wolcotts for inspection before this test. This engineer also said that the circuit with the Bendix tubes could be capable of 400 watts per channel with this mod, provided the power supply will handle it. I like the amps a lot even as they are, but the 6922 driver tube that comes in them is TERRIBLE! Not just poor, or undesirable, but just plain awful. The Siemens CCA 6922 was a major improvement, and I am still going to try the Mullard 6922 as well. I have Telefunken AEG EL-34 tubes in there right now, and they are much better than the Sovtec tubes supplied from the factory. I have a complete set of Mullard Dual Getter EL-34 tubes from the 1960's coming from a tube dealer, and will try the test with them next. I hope my friend with the Vandersteen 5's will run these amps to death for the next two weeks, it will be nice to try them (more) broken in as the next test, then with the Mullard tubes in the outputs. I am supposed to get Telefunken and Amperex 6GW8 drivers for the Wolcott, to replace the nice (but not ultimate) Tungsram that came with this unit. I hope in the end, that they will perform to a level that I will not concern myself with anything except listening to the music they make. Until then, lots of homework to do.

These were the best Amps I had in my system however they have broken down twice in the last year. That was enough for me. I think everyone else has had 0 problems. I am auditioning the Aloia 1301 inductive amps as there replacement.

I am not so sure how these Amps match up to all speakers. With Dunlavy V's they seem to lack power to drive the bass.I replaced them with Aloia 1301 inductive amps to get the awesome control. I've talked to another person who had the same problems with Wisdom speakers. I was wondering if the person trying them on the Vandersteen's had the same problems
