name that tube


I have a RCA 5 pin, coke bottle rectifier tube that is either a 5v4 or a 5y3. However, it is not marked. Would the number of pins identity which one it is? Thanks.

Audiofeil,

I know you know much more about tubes than I do, but I'd always read (or at least thought I had) that you could use a 5Y3 with either a 2a3 or 45, and that it is the 5v4 that should not be used with a 45 triode.

Am I mistaken?
