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.

The Paramours are a great product for the money, but they are a "budget" entry level amp whose parts have been speced to satisfy a relatively low price point. In my mind this raises a question about how much money one would want to spend upgrading Paramours versus starting over with a more upscale product like the Paraglow or a Welborne DRD 2A3 amp. Each upgrade to the Paramours is only an incremental expense, but you could increment yourself to something that ultimately costs more than it's worth. I did the Bottlehead iron and caps upgrade, which is well worth the price, and upgraded to a Sovtek 2A3 (you really should have a backup pair of power tubes anyway). Beyond this I believe I would try to find a buyer for the Paramours and replace them with a Paraglow or a DRD.

It's been a few months now and my Electro-Harmonix 2A3's have a few hundred hours on 'em now. You're right - They've picked up that blue glow. Just wanted to check back in with you and let you know. I still remember you're the one that recommended these tubes, and a good recommendation it was too. Thanks.

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
