    A good Speyside is my personal fave!

    A tidy build and I love those eyelet/terminal thingys.

    Building A Small Amp in A Hammond Box Instead of a Chassis
    Well yes. It is certainly possible - I never experimented it for guitar amplification, but it works well for Hi-Fi with a Hammond 1550J aluminium enclosure - at least under mono block form :

    Thanks @James Knox ! :)

    For use in a combo, the clearance angle of the sides can be a problem since all the faces won't be perpendicular. It may be an issue for housing the box straightly in the cab...

    I’m glad I tuned into this thread. So many impressive builds as examples. It’s inspiring.

    I did this on a Hammond Chassis a few years ago. PP EL84, variation on an Orange Tiny Terror with an effects loop. Point to point so the chassis was actually pretty roomy. It’s a 12 x 8 IIRC. Simple plywood box with mitred corners and maple veneer.

    this is one of Rob's Deluxe Micros in a 7"x 7" Hammond enclosure.
    It's has some "unorthodox" qualities, like the board mounted upside down to the cap, and some hook-ups to the bottom of the turrets.
    Of course the enclosure is then screwed to the base, and the board is then "components-up".
    This configuration would not be "repair-friendly" - but fortunately it works fine and sounds great as is.
    I laminated the entire inside of the base with vinyl, plus put a passive standoff on the bottom of the board, to prevent any sagging/shorting.

    This was a re-fit from an earlier config that I didn't like - you can see I did some rough machining of my own PT mounts to make things work.

    Shockingly, given the little capacity for lead dress, this thing is real quiet.

    my 2-cents - punches for the tube sockets are worth every penny.

    Wow - love that! You got the Jewel Lamp Assembly in, used a normal fiber board and I really like the OT on the inside.

    Is it “headphone” only?

    nope - there's a speaker/cab jack between the headphone jack and the PT.
    you can see it behind the V2 shield/case.

    Like I said before, these examples are inspiring. I’ve lost track of what my next fall/winter amp project will be but this is giving me some pretty clear direction. I love the clean look of it. Just fantastic.
