I am a Newb to posting, but I've been using the information from this site for a while now. Thank you in advance for all the help you've all provided.

Info: I have a Seeburg LS2 Gem that I inherited from my Grandfather. It has been in garage storage since 1999, but was working for many years before that.

Issue: Missing Diodes on the circuit board of a SAS2 on a Seeburg LS2.

Problems: Once the mechanism was lubricated and adjusted, I was having problems with the mechanism working intermittently after the power has been on for some time. Second Problem is that when it would enter into the 33 1/3 Play mode, it would just flat out stop.

This is what made me pull the SCC8. As soon as I opened up the SAS2, I knew exactly what was wrong with the 33 1/3 play back (see attached image).

I'm sending the SCC8 to Bill Bickers to have him work on it. There are signs of overheating with the SCC8, that's why I feel much better letting an educated man work on that.

Question: What are the replacement diodes I need to find. (Hopefully I can get them on clearance from Radio Shack.) The two visibly bad diodes are the CR2104 (part number 309384) and CR2105 (part number 309476).

Once I replace those two I will check the rest of the board with a meter. I'm sure I'll find some more that are bad.

1N4002, or better is fine--however, I would, at minimum, replace all caps, and would update it to a -2 board, if sent to me for re-building.

Good advice Ron.
Those diodes are blown apart, both.
So my estimate would be something "down the line" that caused them to explode.
Could be anything.
