Up to runeight & wiatrob I guess... An experienced builder could likely build this in one (busy, uninterrupted) day, but perhaps best spread across a couple.
Runeight will provide BoM which currently requires a Mouser & small Digikey order assuming you've a tube socket & 1A+ 24VAC adapter.

Been using Compact Tube Hybrid (CTH), like MrSlim's CHamp... There is the Fender thing & its runeight's call.

We spec the small Alps RK097 in BoM, with Panasonic's 12mm EVJ-Y10F03A24 as a "large" alternate. Here's idea of frontpanel clearance:

Other than the small TO92 BC3X7 devices (which we want to keep happy), the only other heaters we have are the tube (handled by its hole), LM2595 heater reg (max: 0.8W disp) and 24V LV reg (disp more than heater reg).
I like to handle heat from the big producers separately from the rest, leaving a nice comfy home for all the other little parts. E.G in my FirstWatt F1/F2 clone I isolated the FET HS so its heat doesn't affect any other innards:
Being fixated on cooling myself, I looking at perforating the sides & top OR bringing some heat external through use of a tasteful piggyback HS for the regs... Something like this but maybe not as tall:
Good luck on the builds guys!
