Bally Dr Who Pinball Machine Time Expander Opto Fix. Condition is New. Shipped with USPS Priority Mail. This is for the one piece that slips into your Time Expander Opto holder and will correct any misalignment between the two optos. Over time the original plastic housing will warp and cause an opto error. This new piece will straighten out the opto line of sight.
This piece will slide in over your old plastic housing. There is no de-soldering.
The piece in this auction is the one on the gray carpet, the main picture. The other picture is showing what the part looks like once installed.
