Power supply finally completed. RF deck sitting on top of B+ supply.
This is a superb video, that depicts how it all interconnects together.
I made an error on the Part 27 writeup. The oem thin aluminum top cover of
the larger B+ box was temp used as a template, and laid on top of the new,
1/8" thick, 6061-T6 top cover for the B+ supply. The oem cover used 6-32
screws around it's circumference. The 2 x identical sized sheets were temp
overlaid, then C clamped in several places, (between holes), then new holes
drilled out.
The new EBM Papst blower is a model G2E160-AY47-01. It's heavy, 4 kg
(8.8 lbs). Rated for 305 cfm @ .9" pressure...when run on 230 vac / 60
hz. That weight hangs from the new, thicker top lid. Here is the data
sheet for the blower. (scroll down for the 60hz performance curve).

Here is the latest part 27 video. Testing will begin next week, time
permitting.
