What a gorgeous amp. How did you do the winged "logo" in the sheet metal?

An externally hosted image should be here but it was not working when we last tested it.

I really liked this one. The "UFO-tubes" (832, 829 etc) makes up nice looking amps.
But that fat tube, the compactron tube, what kind is that?

Is this OTL? or are they hidden inside?

Arcturus 27's and 80's as rectifiers. All in all pretty standard.
Funny to see the different opinions.

Like others, I wonder about the fan. Not for aesthetics or the sound impact of the fan itself, necessarily, but I hear the 27 is pretty microphonic, especially the blue. It'd make me leery of using a fan purely from a sound perspective, even with sorbothane bushings. It may not be an obvious microphonic, but I'd think it might excite some noise that would impact the sound at least in subtle ways.

But I haven't yet built with a 27 (hope to fairly soon), and I DO like the blue Arcturus look.

Fan is at half speed, in rubbers.
In real life it isn't a problem.

What was problematic was a peamp I build a couple of years ago.
Loooked (in my mind) gorgious, but had to disassemle it.
It produced to much noise, due to bad lay-out etc.

But it sure looked pretty...

He he he, we've got you now. Do you have amps 2 and 3 in the works? Looks great, let's see underneath! How do you like it?

Indeed. And you had both smooth and nipple blue 27s?
