1979 Williams Flash SS
Rebuild
This phase was a little nerve wracking as unlike my other restorations, I’ve never seen the pin work beforehand.
Some of the long-pole activities during this phase:
Replacing all of the older electrolytic caps on all of the PCBs, burning new ROMs, and reflowing new solder on all board connectors.
Re-pinning all wire harness connectors. Talk about tedious!
Re-soldering hundreds of wire harness connection points to the correct parts.
Laying out the locations for newer, 1990’s era flipper assemblies (x3) to replace the originals. Actually had to modify the flipper base for the upper flipper but cutting away a small portion of it with a Dremel tool so as to not interfere with a lamp socket. Flipper action is sooooo much nicer with this 90’s style Williams flippers.
Replacing the old, unreliable horse-shoe copper contacts for the drop target registrations with new magnetic sensors (and then dialing them in for accuracy). Not only is the scoring 100% accurate now, but the actual performance of the physical dropping action of the targets is, in a word, crisp. Fantastic upgrade.
