I've been to Germany - even took a little German in highschool. I can even make a little sense of what he wrote. But I just used babelfish (http://babelfish.altavista.com/) to translate. No reason to force english on everybody when it's so easy to translate... even if it comes out alittle funny sometimes. ;)

Ich bin nach Deutschland gewesen - nahm sogar ein wenig deutsches in der Gymnasium. Ich kann sogar sein wenig sinnvoll von, was er schrieb. Aber ich benutzte gerade babelfish, (http://babelfish.altavista.com/) um zu übersetzen. Kein Grund, Englisch auf jeder zu zwingen, wenn zu übersetzen so ist einfach..., selbst wenn es aus dem alittle kommt, das manchmal; lustig ist ;)
 
Not that this'll help my argument...

"I was to Germany - a little German in that High School even took. I can be even a little meaningfully of, which he wrote. But I used straight babelfish, to translate (http://babelfish.altavista.com/) in order. To force no reason, English on each, if to translate like that is simply..., even if it comes from that alittle, that sometimes; is merry"

Anyhow, a picture's worth a thousand words. That's a freakin' cool lookin' amp!

Hi,

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...

I'm assuming the "A"s with +&- around them are that.

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.
