    Don't get too excited, it hasn't made a sound yet. Right now it's just an impressive looking paper-weight :D

    I've built over half a dozen variations- heads, combos, high gain, EF86, octals, etc. It's a very simple platform, sounds good and is excellent for modding. Have at 'er Lincoln.

    Funny you mention EF86. I have a drawing on my desk right now for an amp called a "Creme Brulee". Real simple little 2xEL84 amp with an EF86 preamp tube and a Vox style tone selector switch.

    I bought one of the Trinity Amps version of this build and as a tool maker with no electronics training, I was able to finish the amp with no problems. The documentation is over the top and the pictures make it as easy as can be.

    Nice job! I like how you braided the wires to the output impedance selector. That is dead secksy!

    Thanks!! I had to watch a few videos to learn how to do it. LOL. The instructions say to braid the wires, but they don't say how

    Another day, another bit of progress. I'm stalled though now. All that's left is the wiring to the output jacks.

    I don't have a impedance selector switch, so I'll either order one and wait, or put in 2 or 3 jacks, one for each. 4/8/16 ohm.

    I do.

    I finished it today, using a later model Marshall selector switch. I just had to "enlarge" the hole a bit. That Chinese plexi plastic smells like nothing I've ever smelt before. Really odd, and not a good odd either. Bizarre might be a better word.
    Anyway, all is well, the amp makes nothing but good sounds, and it doesn't hum. I haven't hooked it up to a speaker cab yet however, looking forward to that.

    One question remains.......head or combo?

    Congrats on the build!

    Either way you have yourself another great build !

    I have to figure out how to do this.

    Well, summer construction season has finally come to a halt and now I can get back to my "fun" projects again.
    I finished the cabinet for the 18 Watt I built last spring. Speaker is a single WGS Green Barrett 12"/25watt.
