I rebuilt the power supply on that Philco UHF converter I got, replacing the selenuium rectifier with a 1N4007 diode. Space for the capacitors was tight, but I got everything in there. It works good, and it works on ch 3. So I don't really know now if the reason it works better is just that it works on ch 3 as opposed to 6, or if the extra amplifier tube is really making a difference. Here's pics of it. On the screen picture, the light and dark areas as well as the horiz lines, are in the picture, but not on the set, I tried taking about 20 pics, but they all had that problem.
