    That is the power supply board.
    Single cap is 32uF 450v for PI, the next two in series 32uF 450v for 16uF screens @ 900v handling, the black parts are BY127 Diodes two parallel chains and the other 4 caps are 32uF 450v in series parallel for 32uF 900v handling. Basically a stock JTM45/100 set up.
    Differences between stock and JH (Dickinson spec.) are the slightly later preamp filtering (32uF and 32 uF vs single 16uF with an extra 10k dropper between them like the '67 spec 100watters, and the tone stack which is 33k/560pF like a split cathode lead amp.
    I really like it and prefer it over a stock 45/100 even though I generally use splittable humbuckers. Does sound very Jimi with a strat tho'.

    Thank you.

    How long did it take to get all the components gathered up for that build?

    I have far too much stuff! Been acquiring stuff for nearly 20years - provoked by wanting to build a better amp than my HR Deville that I was gigging.
    Several builds lying around and a couple of restos. Pick up interesting bits here and there.

    China hats to keep the KT 66s and the silicone dampers to stop the springs rattling on the tubes - makes them mucrophonic.
    Gave the amp a noodle today with a strat.
    One of my best amps - as nice as my 64 and 65 JTM45s
