[Boatanchors] HEP-170 Diodes (oops)

[Rob Atkinson]

any silicon diode that can handle the PIV and current will do.  I'd
avoid selenium.  There is a lot less voltage drop across a silicon
diode so you need to measure the v. with one and then the other, and
with the current draw, come up with a series resistance and power
rating that will get you the rectified design voltage that was
intended with the selenium.  I usually go overboard on the power
rating so the resistor doesn't get real hot.
