Replacement 50W Flouresant 12V/120 ballast

[KP Marsh]

Hi Group: I need help locating replacement ballasts for the 12T48 50W flouresant lights over the sink in our 1989 PT40WB. The original ballasts were Magnetek-Triad #9200 or PS-20 models. Magnatek is no longer in business and its successor does not have a clue where to find replacements. Has anyone on the forum had to replace these ballasts either over the sink or overthe dinette?. If so where were you able to find replacement parts? Does anyone have a suggestion for a modification, say to LEDs as a substitute? Thanks, Ken Marsh Towanda 89 WBPT40 Currently workamping in the dark at DC Booth Historic Fish Hatchery, Spearfish, SD
