I have seen a few posts about this. Is there anyone that has the replacement procedure to Silicon Diodes in a little more depth? I will also replace Caps 1000uF 50V should be good? I have the schematic. Is it just as easy as putting the Silicon Diodes where the Selenium diodes go in the schem? THX

It should be that easy. Mechanically you might need a solder strip.

You really could very probably get away with soldering a silicon diode across the old selenium rectifier, using it as a tie-strip. The silicon is lower resistance so the presence of the selenium rectifier, especially if it has gone high-resistance (that's what happens to nearly all of them when they get old), won't make any electrical difference.

Anyone know if any added resistance is needed as only .7 across a diode? or just the IN4007s. Also do any of you use 2 diodes per side or is one good enough. I suppose I am over thinking.

One diode is enough.
