myLife: Williams Sys 6 Gorgar Pinball repair notes

Here are a few things I’m making note of as I’m learning about pinball maintenance and repair.
Items may be meant for Williams System 6.

1. Consider using #47 bulbs to replace #44’s in the backbox. #47’s produce about 40% less heat. It’ll ease the heat applied to your backglass.

Need to repin master display:
Replacements would be AMP (Tyco) “Bifurcated Leaf Connector” series —
640136.
6 pin edge connectors — AMP 640136-6 (similar to Molex 09-01-6061)
9 pin edge connectors — AMP 640136-9
15 pin edge connector — AMP 1-640136-5
18 pin edge connector — AMP 1-640136-8

Uses AMP’s long Bifurcated (split) contacts which are quite similar to Molex
08-03-0304 (as used in Gottlieb). I’ve got a bunch of plugs on order but
still haven’t found the right contact or keying plug’s yet.

Keying plugs are AMP 640180-1
Contacts are AMP 350011-1 (Brass) or 350011-3 (Phosphor Bonze). (-2’s are
gold plated – avoid).
