Noob question... for the Classic Tone power tranny are you just doing an artificial center tap for the 6.3v heaters and grounding it at the power supply star ground?

The first three valves are on 12vdc regulated headers. These are the ones most susceptible to picking up heater hum, and the smooth 12vdc makes that a non issue so no need for a center tap, or artificial center tap.
If I were not running dc heaters I would have made an artificial center tap, but ran it elevated instead of to ground.

Man, I was hoping the would be the case by now, I have a little more wiring to do. But I can't catch a break, I had to fix the pool pump/filter, and the AC condenser on my wife's car exploded so I had to fix that this weekend too.

man, this is so freakin' cool. wish i had the knowhow to tackle an amp build, let alone one that seems this advanced. while i'm completely electronics inept, seeing the gut shots always gets my juices flowing.

Robert @ www.valvestorm.com
He makes the chassis too. I'll be getting (hopefully) face plates from him as soon as he finds a new shop to do it, the old shop he was using closed down.

Ah that's a shame... I knew the place he was using went out but didn't know he hadn't found somebody new yet. Hoping to get faceplates for the project chassis from them if my build actually ends up working

how about adding a variable negative feedback like in the be deluxe?

It pretty much has that, except its on a switch that switches between the 4ohm and 16ohm taps. I played around with the response type control on my other build, while it was cool, it's just another knob to keep track of, playing shows someone is bound to hit it. Also I prefer the sound of going directly to the taps and just use a 47k NFB resistor.

I have had the most challenging issues trying to create a faceplate after the fact.
Hopefully there is a template or standard spacing to aid the reproduction.
Curious how you go about it.

Normally I would not do it this way. But the chassis is made by valvestorm, and they are the ones making the faceplates too, so they are able to make sure everything lines up perfectly.
It's pretty awesome because all i did was take an image of the chassis and label the holes I'm using, Robert took it from there.

That is quite an impressive build.
There is a lot going on in that amp. Lately I have really been appreciating how reasonable most amps are cost wise when you realize how much time goes into building a quality amp.
Just wiring up a MV can take you 2 hours to get the parts ready with shielded wire and such.
I am GASSing for the 50 watt transformer set for sale, but after building about 10 amps the other half of me wants to buy a nice amp and then just play.
