New 47 bulbs in the coin door - nice and bright - for eight minutes.

New 47 bulbs in the coin door - nice and bright - for eight minutes.

Then BAM - both of them burn out.

This is on the coin door of my Crazy Climber cabaret; looks like original power supply.

Wrong bulbs for the voltage?

EDIT: Also, it hummed like a nuclear sub before the bulbs burned out. (Well, not that loud. But louder than normal.)

Hmm, that style socket is probably not original? Did you wire the sockets in there yourself? Usually, #194 lamps are used in the coin door lights....

probably... Don't remember off the top of my head, but #47 are 6.3V bulbs. There's a decent chance your coin door is wired to 12V. The 12V equivalent is (I think) the 1813.

Are you talking specifically for Trimline cabarets, or in general? `Cause I've got #47 bayonet bulbs in two other coin doors right now. Did Taito minis take wedge bulbs instead?

Didn't wire them in myself - they came that way.

I think you might be onto something....

Right, that would be of the same socket type. The site above doesn't show those but the specs say:
#1813 MINIATURE BULB BA9S BASE - 14.4 Volt 0.1 Amp T3-1/4 Miniature Bayonet

I made the exact same mistake in my OMG Pizza thread this fall. I mistakenly used 6v bulbs. Burned like the sun for 5 min, and they were cooked

Did you replace them w/1813s?

No, I metered the sockets and when I found 12v, I used automotive wedge bulbs from my parts department @ work.

If you ever pop a bulb in and it's blindingly bright, just pull it back out before it burns up. You're feeding it twice the voltage it's supposed to get so it won't take long to cook!
They're cheap enough, just keep a box of 555,161,1813,47 around and you'll pretty much be covered.

Having a "kit" with all of them does sound like a good idea.
