I'd also check out the M and L relays - they're the ones doing most of the work, pulsing on and off five times in a closed loop with the EOS reel switches...

Switches clean and gapped? Are the armatures clean and moving freely? Armatures not magnetized? Score reel EOS switches look good?

A good reference for switch cleaning and proper gapping:

In short, when a switch closes, you want the long blade to move the short blade a small amount, causing the two contacts to "wipe" across each other. Clay describes it fully in the reference above.
