Simple HT supply build

[Mike Watterson]

I've assembled the miniature 11.5V transformer (double bobbin with obvious plastic, and thermal fuse in primary) to a simple smoothing circuit. Bridge, 220 μF 35V cap, 22 Ohms series and finally bigger 20V cap (1000 μF). No load is just over 16V. I put an 470 Ohms and LED as a load and it's below 15V (maybe 13.9V or something, I forget).

I don't think a regulator is needed.
