There's a guy here in the Netherlands who understands transformers. He might know what you need. http://www.marble-amps.com/transformers/

Whoops, sorry, didn't read the long copy. Thought you were still looking for transformers. Great score on the tapped pots though...

Yeah, I looked into how my Carvin achieves its 50% and 25% power modes and it turns out that it doesn't actually drop any tubes to do it. (I think) I read somewhere that the 25% setting switches to triode operation and it certainly succeeds in dropping the volume and headroom. I'd describe it as way less than half volume. At full power, full volume the thing shakes the entire building but in 25% mode it's totally "bedroom" level even cranked.

In short, I think you're onto something there! I haven't read through that entire webpage yet but it's still in the queue.

And in other news, a package just came in from Down Under...

Just in case you've never used aviation spec Teflon wire before, good luck cutting and wrestling it into position! It's very nice stuff though, I'll be watching to see how you deal with it - from the perspective of me learning something that is.

Are those Russian 6Н2П?

If so, be aware that those have a different heater pin-out to the 12A_7 types. (6.3V filament is between pins 4 and 5. 9 is the shield)
