it's certainly not a beginner project !
Without the OPT it's possible to direct drive ESL !
The anode load could be resistive or even more iron.

I hope we are not going to see new threads in all kind of languages

fdegrove,

I'm assuming the "A"s with +&- around them are that. Otherwise it would be difficult to run class A with 3k on the plates. I could always be wrong, so I thought I'd ask.

Thing is it runs in class B not A...

Bernd was kind enough to send me an e-mail about the amp with a link to a gallery where the design is hosted.

I must say this thing scares the living daylights out of me...

Have a look:

DIE MOEHRENBUDE...

They look like CTs for the heaters to me but I'm not sure either...

Cheers,

D'oh. Those are, of course, the mA meters. Must. Jumpstart. Brain.
Wow. He's running those full tilt? I wonder how he damps the clanking when he walks. That's one heck of a beast.
I get "funkenstrecke" translated as spark gap. Now I'm scared. I was wondering how he'd deal with the transformer kicking back during cutoff.
I am duly impressed and suggest considering prolonged psychological counseling.
