Bought a Williams Comet last week. Some of the playfield lights weren't working.

I traced it down to a bad 2n6427. Don't have one.

I have a drawer full of the following:
2n3904
2n4401
MPSA42

I'm impatient of course and want to get it going this weekend instead of ordering and waiting.

Would any of the three be a workable substitute?

I'm running LED's so the current draw should be a lot less.

thanks,
John

Thanks everyone. Of course I found a bag of MPSA12, no 13 or 14.

G-P-E Will MPSA12 work???

Thanks a million. I'm gonna get an order in for the right stuff next week. I've had those MPSA12 stashed away for 15+ years. Don't remember where I got them or why.
