[R-390] R-390 CR-801 replacement

[Fred Moore]

I did find one with a mounting hole that fits right in.  I got it at Radio
Shack, hahaha.  

I will find the same thing on Digikey for you over the weekend and reply
again.  Indeed those copper oxide rectifiers can go bad on the R-390.  -Fred

Good morning gents,

While we are on the subject of the R-390...
I would like to replace the Selenium rectifier CR-801 under the power
transformer with a modern bridge rectifier. 
The problem I am having is I can’t find a suitable device that is small
enough to fit ‘and’ has a mounting hole.  Everything I have come across so
far have small plastic cases with no mounting hole. 

Does anyone have a suitable part number I can search for? I would be very
grateful. 

Best regards 
Ken
