Incidentally, my 9 out 10 Collins 20V-3 is for sale.  

I am asking $8,000.  I have one prospective buyer but he could drop out.

See the pictures on the CRA website in the Album section entitled: "Heavy
Metal is Not For Everyone."

Thank you

I meant to suggest that I have some of these solid-state rectifiers but do
not have the numbers in my head.
 
I replaced my 575 rectifiers with them.  Please inquire.
 
Thank you

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

All,
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,
73,
Pete, K5PZ
