No problem. Tomas have found a Hammond power transformer with the same specs as what he would have ordered from Sowter. With chrome silver side covers, they look the works and I can't wait to see and hear the amp. 11w in triode mode and a bit more in UL. I'm not power hungry but headroom and a quiet amp is always welcome.

It's the output transformers that matters to me for SQ and still waiting for Sowter to deliver that. Should be soon.

Sounds like a perfect fit, the chrome will match the Sowter transformers well! Looking forward to seeing it completed. 11W will make your speakers and headphones sing :)

Maybe I should contract her services to name my upcoming amp by @A2029
To be clear, I do have a working name, and couple others I am considering, but who knows - maybe she would have an even better name... :wink:

Idk, my other amps have pretty goofy names LOL this one is definitely the coolest, I have no control over it.

Hammond and Lundahl power transformers in the V6 Thunder.

Apparently the Sowter output transformers are ready for delivery for Red Dwarf.

That's exciting, going to be some very nice SET amplifiers popping up on Head-Fi very soon. Finally your power pentode collection will be unleashed!

Yes a little wasted in the DAC - but still been fun trying them all.

Interesting Leftside. Why are you having both Hammond and Lundahl power transformers in your next amp?

Previous/current amp. V6 Thunder had a totally separate chassis just for the power. It needed a Lundahl LL1651 and two Hammond 10V 185G20 :)

Lundahl power and Sowter output in the next amp. Simpler design.

I bought a bunch of 6F5GT tubes for chump change, think they were $7 each. Thought I'd give my 6F5G a break and try some out.

Matched this pair on my curve tracer, JAN Sylvania 6F5GT from 1952.

Sound pretty good! Will give them some time. The grid cap leads look a little long with the more squat GT type, might consider making a shorter set for the GT and metal can 6F5. This amp makes for a good night light.

Going to have a big shipment of 801A coming to me soon, probably five or six new pairs, including another graphite plate model, so looking forward to playing with those.
