Oh, yeah! I forgot about that! Your Valve Art's are quieter? That, plus being blue, make's 'em quite a catch! I need to buy a few more so I can get a pair that aren't noisy. As an aside, totally off-topic, I'm bustin' at the seams about a new project. You're gonna love it, as are all the other good woodsmiths. I can't wait to show and tell...

Why of course, you're the controversial and elusive Till E. By the way, did you see the posts on the Craftsmen forum about a FAQ? I remembered at Lima, you suggested a video FAQ so I made mention of it. Seems like a pretty cool idea, to publish a how-to audio guide online, in print and on video. And one more thing. This relates to nothing, but it's kinda fun. Check this out: 1000 is a thousand
1000000 is a million
1000000000 is a trillion
1000000000000 is a quadrillion
1000000000000000 is a quintillion
1000000000000000000 is a sextillion Anything between that and infinity is a zillion. I wanted to clarify the actual quantity of the number "zillion". Just trying to be helpful.

Hey-Hey!!!,
You don't need any particular type of Iron. Stay class A, choke input PS, and no 'lytics. Of course good Iron helps a lot... You are looking at the last amp I have assembeled/designed. Part of the Iron is salvaged from one sort of PS or another. Outputs are Heyboer's copies of the Peerless S265 with a few mods for this particular circuit. The finals are HY69's, a Thoriated Tungsten DHTetrode. The front end is an E-Linear cascode diff amp. Ec2 referenced to the cathode node instead of the usual ground through a voltage divider... It makes about 15 watts.
regards,
Douglas ....damn Thrintun!

and this is an example of an E-linear amp's circuit. No loop NFB. Single B+ supply. It is the only thing I can think of that resembles a new valve circuit. If anybody can find me an example which resembles this, I would be very grateful.
regards,
Douglas
