The YOKE connections was the final culprit. Set was fixed! I had to rework
all PC boards for CSJ's (solder) and make a deflection board (hard plastic)
to keep a drop or two of coolant off PC boards (saw a little on board) and
go thru and do several alignments and a few other things... Was a major pain
in the butt... but the YOKE plugs were the final fix! Set looked great and
played for days w/o no problems after. Thanks to all!
