I've recently aquired a Pilot tv37 - I know it used a 3KP4 picture tube but this one came with a 3BP1 tube addapted to fit the 3KP4 socket - I havent powered it up yet and am curious weather or not the 3BP1 will work? - Some one before I got the set made this change - Can anyone give me some information on this???? Thanks Guys

The 3BP1 is green, more suitable for oscilloscopes than TVs:

It should work, but won't be as much fun to watch.

The 3BP1 is easy to find since it was used in most 3" scopes. However, its rating is quite a bit lower (max voltages) than the 3KP4 or 3KP1, so the Pilot37 will exceed the design limits of the 3BP1. I don't now if this reduces the lifespan or what? Lastly, the dimensions and socket of the 3BP1 are different than the 3KP4/1. Since it is a little shorter, it will fit it in the Pilot37.
