    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?

    This is just one reason I am glad I joined this forum....

    John the granite looks outstanding and just the chassis are spectacular. The detail work outside makes me wonder the detail you are going to take on the wiring which no one will see but you and us (via pictures).

    Updated pics with the binding posts, input terminals and EIC connectors in place...

    Wiring will begin as soon as I research what will be best for them.

    The tubes will be auto-bias and there will be switching for ultralinear and triode modes...

    It appears by looking at the photographs I have that the wire used is common copper wire. I am looking into silver.

    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.

    You got balls of steel. Will these ship with a forklift included for placement?

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

    Those are some nice looking amps you are building.

    I would love to hear them some day.

    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.

    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.

    Pics to follow on Monday or Tuesday next week!

    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.

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

    ^^^what he said!:D:cool:

    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".:):)

    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.

    Stainless steel and granite is manly, adding wood to the mix says kitchen ****.
