Thanks Kevin,
and everyone else for the help,  I have all schematics
and original manuals for the rig, but didn't have one for the
PSU. Ha, Murphy's law

I think the reason the SCR finally gave out,  was I kept the radio
on 24/7, and there is a lot of heat in it any way. I need to make
up a 12V power cord so I can power it externally.

And Talk about good luck, I also noticed I can buy the SCR on ebay,
NEC brand.

Thanks again everyone for all the help.
