I also picked up a RFM recently. The CPU fan was already noisy. After cleaning out the CPU box (the fan was rubbing the power cable insulation) I replaced the CPU fan and converted an ATX power supply I had. Had to get a new switch for the front of the CPU box, but the whole operation was pretty easy and will last for years.

I've identified 7 cherry switches that need replacing. i just ordered the full assembly (A-17813) and new diode. In the meantime it makes the game more challenging to play with 7 switches dead or intermittent.

Aside from a couple missing/broken plastics, one problem I keep having is the bulb above the left outlane breaking - even with a new tight rubber. It looks like with the outlane full open there isn't enough room for the rubber to stop the ball from striking the bulb.

Quoted from dieseldogpi:

You don't need to get a new switch, you can use the original one. Follow the instructions on the site nosro linked

The original in mine was soldered and was more trouble than worth to clean up (the switch in the instructions don't look like they were soldered). I could likely have even done without one, but I had a switch laying around and the machine had to go thru other troubleshooting where the switch came in handy.

Quoted from nosro:

but shouldn't this spot have double rubber?

You are correct sir...ty.

interestingly the one plastic I'm missing is the one over that bulb next to the center targets. Despite the number of times the ball flies into, over and even onto it, that bulb hasn't broken on mine yet. But the bracket idea sounds like a good solution, especially of it has a brighter LED.

I've placed the second bands on it and replaced the bulb (left lane fully open). Haven't played it much since, but so far no broken bulb.
