Re: Just another amp..
Art D. would have been proud very proud. Very nice. That ess....ess....escutcheon (sorry I have allergies to weird english words) begs a small O-scope display in there showing the audio signal or easier, two VU meters with the needle fulcrums at the outside centerline and the tips pointed inwards waving past each other..

Designed and made some nice woodwork around an ancient Howard dialplate (escutcheon) in Art-Deco style..
Love it or not...

how can a triode amp be "ultra linear"?
Triode/Ultralinear would indicate he can run it in either mode.

I was about to do exactly the same thing Darn, you did it first now !
Kind regards,

A little tube-stage, a huge supply and a lot of MOS-fets on a 10mm thick black-anodized aluminum frame (CNC-ed by myself) . Good for about 2x750WRMS/4Ohm (Yes 1500Watts RMS in total )

6550 is a pentode (or beam tetrode) which I wired in (switchable) triode/UL. The custom made OPT has a 43% UL tap.

As you live at the other side of the world, probably no-one will notice..
You have a Howard escutcheon too??
Kees
No, just a few blue and red leds for status. (blue-operate red-standby)
With some difuser-glasses i managed to get a quite equal illumination of the whole surface behind the eye.. It realy looks very nice so. The blue is that bright that the luminosity is equal to the average in daylight. The red is deep and visible but equal in evening luminosity.. At night the switch illuminates the background so you only see the shape and the red eye..

Like this?
Or would you prefer to turn it around? (Yes, i know the aspect is wrong and the alignment too)
