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.

Here is an Archer datasheet for the DT-1704:
No info on suffixes, though. :-(
This appears to be the same datasheet:

Hi Frank, Thanks for the links. I had found these on the Internet also, but as you noticed, they don't explain the difference in the suffix letters. I am hoping to find someone with an original databook which gives more info. Thanks again, Kevin.
I can't tell you where any documentation is to clarify this question. I can only offer that perhaps these suffixes denoted slight packaging differences, or generations. Vacuum tubes added suffixes for such variations, but the functional specs were almost identical from generation to generation (unless one used a tube to take advantage of some specially tweaked parameter in that specific generation)

Wikipedia states that Tung-Sol's business was taken over by New Sensor Corporation:

John and Frank, Thanks for the replies.
If I can verify that the "letter" suffix is a change that does not affect the operating parameters, then I'm good to go. I only want to know because I am trying to determine if all suffix numbers all inter- changeable. In other words, can a DT-1704C be used in place of a DT-1704B and visa-versa.
Thanks again, Kevin.
