According to the original data sheet the 8894 is more or less standard
7 segment VFD. clipping from the TCA Data Cache.

Awesome thanks for the datasheet!  It looked to me similar to the other what I call floating VFD on mica type tubes like a handful of others.

Hi Bill, the DT-1704A, DT-1704B, DT-1705A and DT-1705B Digivac tubes actually had true floating segments without mica sheets, the later DT-1704C and DT-1705C tubes implemented the mics sheet, probably a good change for reliability.

I love these tube with and without mica.  When I first saw them without mica I had to have some because they are unlike any other VFD I've ever seen!

A clock was posted with the colons.  Love the spiral.

 

I found them to be:

IV-15 or DM160 or 6977

 

I bought a bunch thinking they were a lot bigger and was disappointed with the size, but still like them.

 

Was surprised when I just checked to see their prices.   Damn.

The spirals are neat for sure!  I've got a bunch too.

If you're referring to my clock, they are IV-15.

I was referring to your clock.  Love it.

 

I was just trying to say the spiral tubes are great – All three are the same thing -- IV-15, DM160, 6977

Theyre similar but I know that the 6977 and iv-15 are not identical

I’m sorry.

 

You are absolutely right, but it would be nice if you could elaborate instead of just saying they are not.

 

Other than being from different manufactures and having different part numbers and many other things, like glass, exact size, etc, they are 100% different.

 

If you relax a little, my point was that all three are Spiral’s.   My comment was regarding the appearance of a spiral and not the exact similarities and differences.

Woahhh calm down... I was just trying to make it clear for anyone reading that they arent the same part exactly- to eliminate any possible future confusion.
I dont have all 3 on hand so I cant give you complete comparisons but 6977s are thinner and longer than iv-15s...

Understood.  Agreed.  I need to relax too.

 

Just to clarify, I was talking about the Spiral and not exact information.  I guess in this group, I should be exact.  😊

Do the colors match between the tubes and the spiral tubes? I remember last I tried the colors were kind of off, but I forget which spiral I used and perhaps my voltages weren't optimal.
