Anyone seen these before? I have some IV26 tubes from 1977 to 1981 that appear to have circular dots instead of the more usual clipped circles (of which I have enough). If anyone has some of the earlier type with the circular dots and wants to do a swap, then I'm all ears... :)

Cheers,

Nick

There are a few different types of these, type 1, 2 & 3 to my knowledge (тип 1, тип 2 & тип 3). Check the text on the back if you can see what type they are.

Pages from some datasheets show two types of indicator elements, round and oblong type, http://www.gstube.com/data/4061/

I can't find a datasheet for IV-26 so I don't know what the difference between the IV-25 and IV-26 is.
Does anyone know?
I have around 700 IV-25 tubes here and they all have non-clipped circular dots.

You can find the IV-25 on Gstube too: http://www.gstube.com/data/1694/

Their general datasheet page is here: http://www.gstube.com/data/
