OV- 15 manufacturing date? « on: January 20, 2021, 11:42:27 AM » Author: Metal Halide Boy
On three of my OV-15`s orignal ballasts there are two possible date codes. One is "CH". I think thats the date. Or it could be "1". Thanks.

Never heard of the letter date codes. The ones they sold here were just numbers. The one on mine is 75M so would be 1975 and is confirmed by the PFC cap.
