Re: Is this Amplifone tube trash?

Have you made sure the high voltage isn't set too high?
If the entire neck is lit like a neon bulb (not just the
heater) you probably have a gassy tube. If so the only
fix for it is to have it rebuilt. If there is any burn in at
all
you'll want a new tube instead.

The only listed substitution for a 19VJTP22 is a
19VJMP22 (and vice versa). Normally I'd say you need
to put in the tube the manual calls for, but since you
appear to have the original tube you should stick with it.
Mounting might be slightly different even though
electrically they may be the same.

A 19VLTP22 crosses with a 19VMFP22 (but not the
other way).
