Hello again from 10 months ago!
It's great to see the site more active than ever. I'm finally getting around to fixing up my BTTF pin and am not sure about a couple things...

1. Replacing a broken switch under the VUK. The old switch was not working well, til finally it stopped working at all.. the diode connected to it was broke.. a quick solder fixed it for about 10 uses. So now I have 2 types of switches on the way..
One is a DataEast switch with a diode already attached to it. It is very similar to the old switch. I also ordered a Wiliams/Bally switch that is also very similar, BUT does not have a diode connected to it. Is there a reason the diode is not included? I ordered both b/c they were cheap.. I plan to use the DE switch, but wanted the other as a backup, and possibly have a higher quality switch.
What can you tell me about these switches that I should know? I am a complete Pinball repair novice and I don't know what to look for.

2. Replacing old lights with LED's.. I do not understand the sizes of the bulbs. The machine I have seems to use mostly the same size bulbs, very small with small bulb heads.. included with my BTTF was a few different size bulbs that I can not seem to find where they go, 3/4 of all the bulbs are too big to go anywhere.
What size LED's should I be ordering? The pinball manual that came with the machine does not list bulb sizes. I am not sure what to do. What type of regular LED bulbs should I order? Colored is not important to me, I just want nice low heat LED bulbs that use less wattage.

Thanks a million guys. This site has been great, along with the pinball parts suppliers thread, lots of nice info.

And... what are 444's and 55's.. or is it 44's and 555's.. I don't know! LOL
Does this have to do with a bulb size/type? I'm assuming it does.

thanks!

thanks for your help

santeh- I did do a search and found where you had replaced your lights in your BTTF. It looks great the way you fixed it up. I can't wait to get started... when I get home this morning I will check out which bulbs I need and buy some.

seal- thanks for the link.. I checked that place out in the "vendors" sticky. great selection.

Soon I will get some some before and after pics, sometime next week, probably later.
