Yea, my tech had never seen it before either. The amplifier chip (the one on the heatsink) had kind of exploded, like broken into a few pieces, and the speaker was stuck solid, couldn't move the cone at all with your hand.
Weird

Thanks! I'm real happy with the end product for a first effort.
The rear g.I. fuse (f108??) Kept blowing, turned out to be a light socket shorting internally. Also had problems with the reel, fter some mucking around,I put my repaired bally/williams mpu back in and it was sorted, I don't know if it's a problem with the homepin mpu, but I'm just gonna run the repaired original board from now on and keep the homepin one as spare.
It's got a lot of plays, and no other problems other then those two. I can confirm that a brand new clearcoat on an old playfield will still get covered in tiny dimples from airballs.
Love the comet leds in the pop bumpers...
Such a fun game, but so simple
