FYI, Richardson Electronics has 575A's for around $350 and the solid-state
replacement for a little over $100.  There is a 6 week wait.

I use the solid-state plug ins in my 20V-3 and may have a few for sale.  I
can furnish the numbers if anyone is interested

Inquire by phone.  (814) 487-4403

Thank you

My friend is having a world of trouble with the mercury vapor tubes in a
Collins 20V-2.
Anyone have solid state rectifier replacements or KNOWN perfectly good 575s
or 575As?
Let me know,
Pete, K5PZ
