Looks like a great project John.
Is the amp gonna have auto-bias or manual bias for the power tubes?
Are you installing a switch to go from ultralinear to triode mode?SDA SRS 2.3TL's

I'd look into a better RCA jack too, if you're going all out, at least used a gold plated copper jack. Vampire, WBT, etc... As for wire, Neotech solid core teflon jacket chassis wire is excellent."He who fights with monsters should look to it that he himself does not become a monster.

The original variant of these amps ship at 47 pounds. I expect these will be in the 65 to 70 pound range.The Gear...

They can be powered off the 15 amp circuit in the house, but when we move, I will have a 20 amp setup for them.The Gear...

Just a bit of an update... I have settled on using a bird's-eye Maple for the side panels. The wood will be stained in a warm, natural color with a satin finish. The rear of the amp is being treated to hand-painted lettering for the inputs/outputs/fuses and other details on the back. The stainless trim rings are being plated in silver.
I have also ordered new tube sockets as I was unhappy with the fit of the originals. Once I have them, I will begin wiring them up, and in a month or so, when Bob is ready, I will fit the transformers and order up some cryo-treated KT-120's.

I wonder how you will be soldering silver / silver-plated wire, which requires tons of heat to properly reflow/attach. It is damaging to the components, if not done properly/professionally.Panasonic PT-AE4000U projector for movies

Heat sinks~they take the heat off on a different path. It's AMAZING how much heat can be dissipated in this way.

I can honestly say this is the most FUN I have ever had in this hobby! Seeing everything in my mind come together in the form of something that will be as much a work of art as it will be functional has inspired me to do even more....
Bob has given his full support and blessings to my doing a limited run of these amps, so long as they are as good in person as they are in pictures. Bob now wants to have me ship these to him for evaluation when I am done. I guess that makes these "prototypes".:):)The Gear...

Or were you going to ship one of them to me, so that would technically make it "one sweet amp" for you.:biggrin:

I'm going to suggest using stainless steel for the side panels since you are using some elsewhere. When using too many different materials things start looking out of place. I would also suggest not plating the trim rings.
