BOTH ARE NOW SOLD. THANK YOU, GENTS!
I ended up getting a factory First Watt F3 recently, and my DIY version was partially done and in a long queue of partially done and not-started projects. Rather than having this take up shelf space forever, I'm offering up 2 "kits".

Kit #1 - F3 Partially Assembled + Transformer - SOLD
NOTE: I got this mocked up on the bench, but it needed some work to finalize. I never got the R5 dialed in.
1 pair main boards - Assembled. See pix. Nichcon Muse caps. Panasonic 3W resistors. Matched semis.
1 pair cap expansion boards - Mix of Silmic and Nichicon Fine Golds
1 PSU board
1 Antek AN-4438 donut & mounting hardware
1 pair bridge of rectifiers with snubbers for the Antek donut
2 5W 10R pots for setting R5
Bunch of resistors for R5 once set. Mix / match with clip leads. Then solder in. I have some soldered in already, but I suggest re-testing.
1 spare pair XRK Lu PCB's + SMD resistors (SMD PCB to main board connectors NOT INCLUDED)
1 spare pair LU's
$175+ shipping
Kit #2 - F3 Bare PCB's + LU's - SOLD
1 pair main boards
1 pair cap expansion boards
1 PSU board
1 pair XRK Lu PCB's + SMD resistors (SMD PCB to main board connectors NOT INCLUDED)
1 pair LU's
$45+ shipping
