[Boatanchors] Neutralization indicator

Hello:

I'm about to neutralize a push-pull pair of triodes.  Re-reading the various methods of building and using an indicator, I had an idea.

A couple of the methods use a coil with a lamp, or a coil   with a transistor and meter.  It struck me that I already have a coil in close proximity to the final tank coil:  The swinging link.

What if I soldered a small incandescent lamp to a PL-259 and pluggged that into the output socket?

Finer minds should know if that would work!
