OG4 dekatron glass diameter

[Grahame]

Hi all,

The OG4 datasheet says the maximum diameter of the glass bottle of an
OG4 is 31mm. A quick check of the few OG4 that I have suggests no more
than 30mm in practice. I'm trying to fit an OG4 through an existing hole
reliably and not be dependant on the few samples I have.

If anyone has some OG4s to hand and some calipers, then I'd appreciate
knowing any measurements that are made and reported here.

A few of approximately a hundred had a width of 30.4mm for the largest with black Bakelite base, 30.5mm with brown Bakelite and 30.3mm with metal base measured with a caliper. Some were tilted somewhat in the bases so if you are having a tight fit those would not fit as they were tilted a millimeter or more.

Hi Martin

Thanks for your measurements and observations. Other people have made similar comments privately (thanks again). The tilt does make using the OG4 in a display function more difficult... I shall continue working with British and American dekatrons for now.
