Quoted from Psw757:I think there are a couple bulbs behind the glass that aren’t 44/47. They are more round and I think behind the frames area.
Yea, those round bulbs are older bulbs. When I go through a machine I put in
all new bulbs. The thing with older bulbs, before some are just ready to burn out,
they get hot. Very hot!, so I replace them all..
The 63s is what I now use. I think it was 81s that use to be easy to get, but 63s
are about the same. Maybe 81s were a little brighter, but to be truthful, I now usually
convert the pin deck sockets to 110V Christmas Tree sockets and use the clear
Christmas light bulbs then run it's circuit with the ball lifts motor circuitry so when the
ball lift's not running (on Game Over), the pin deck lights turn off. Saves on electric
and bulbs..
Yes, for the most part, #47 bulbs are pretty much the norm over #44s. When buying
#47s, I buy 1,000 at a time to get a better price. Makes it a little easier on the pocket
when changing them all out..
