[AMRadio] Capacitators needed

[Gary Schafer]

Hi Bill,

Checked ebay and didn't see anything yet. Saw a couple of oil caps though.

I hadn't heard that it was ok not to use equalizing resistors with a string of
electrolytic caps ?

Not using resistors or caps across diodes I know is ok to do. With the newer
diodes  they all now have an avalanche area that they conduct at with reverse
current so they equalize themselves. From what I understand they have been
made this way for about the last 15 or 20 years.
