Hello all, can anyone please help?
I have several Tung-Sol VFD tubes. They are all P/N DT-1704, but some have the letter A, B, or C, on the end of the number. (IE: DT-1704B, etc). Does anyone have a datasheet for these tubes or can you tell me what the letters designate? I'm looking for any documentation that describes the difference in the letter A, B, C used in these part numbers Thanks, Kevin.
