putting a modern rectifier in place of the selenium WOULD cause the
output to increase. And cause coil overheating. As previously
mentioned, selenium has a higher drop. We used to see this on old
Tektronics O-scopes (Circa Tek 545 era)
The seleniums would go bad, and you ALWAYS put dropping resistors in
with the new style replacement diodes. >>
Yes, but he had DESCRIBED the bad rectumfryer as a "little black block with a
1/4" hole in the middle". Sounds like a 20-30 A. "bridge" (Si.) to me!
