Bruce, that looks stunning! Your amps sound great too - That model is a game changer!

It looks like the "podwatt", but that's only 5watts per channel.
I'm looking to build another tube amp (kit) this winter, to power a pair of 7pi I'm building.
Perhaps I can go with some mono blocks.
Wayne, if you don't mind me asking,
which "Oddwatt" amps have you listened to with your 7pi corner horns or your 4pi's?

I've run Bruce's Podwatt and Oddblock amps. The Oddblock had KT120 tubes in it.
Both are really good amps. Like you've said, the Podwatt is a relatively low-power amp, but it's enough for any models of my speakers. I still like the Oddblock better because of its ability to deliver more dynamic range. But the Podwatt will surprise you.
Bruce's amps all sound like SET amps, but they're less finicky than many of the SET amps on the market. Many SET amps have a tendency to drift as their tubes age, sometimes to the point of overheating biasing resistors and popping coupling or bypass caps. Bruce's amps don't do that.

BTW I was running my system just yesterday with the mini mono blocks which are really 1/2 each of the newest Poddwatt. I have always loved the sound of EL84s and these amps don't disappoint. They are just sufficient to drive my Martin Logan ESLs to a comfortable level...I would not use them for loud rock as they don't have that level of power. ]]>gofar992017-07-13T22:02:20-00:00Re: Something new on the bench

When you say "mid size amps" are you referring to the series 2 Octals?
Those are the mono blocks I was considering, using kt88's.
Wayne's 7pi's are 101db sensitivity, so I'm guessing that's plenty of power.]]>johnnycamp52017-07-13T23:33:12-00:00Re: Something new on the bench

I really like the 6550 / KT88 tubes. And with what Bruce has found on the larger tubes, that makes it even more of a sweet spot for me.

I would think the current troubles with the kt120's will pass.
Is TUNG-SOL the only current manufacturer?
I have decided to go ahead with a pair of OddWatt Odd Block series 2 octal using kt88s.
It looks like it should be a fun build.
I agree with you about some current SET amps being fickle.
I've had my own issues with a kit I built, started blowing fuses (after around 200 hrs.), needing a very specific rectifier tube to correct it (EH 5U4GB).
