A Little Flat Tube Fun

[jr_tech]

I suspect that the small magnetic deflected tubes actually offer better performance. But the "fat neck" to provide room for the deflection plates and the curved screen, which likely reduces deflection defocus make this tube very unique. Do you have a 913? I see them once in a while on eBay.

They were used on the RCA Type 151 oscilloscope. A picture of it, both outside and inside, is here:

I have two of these scopes.
