The meter has died on my military TV7D tube tester. I was unsuccessful
when attempting a repair. It appears that the moving coil is open.

If anyone has a junker that they could spare the meter from, I would
very much like to hear from you.

Thanks,
Larry W4LK

There are still people who will repair meter movements.

Try Bob Larson at Larson Meter Craft.

Hi, Larry
I can't help you with a replacement meter,
but I thought you'd enjoy seeing
a website where the owner, Dieter, rewound a TV-7 meter.
Step one was to run a blowtorch over the face of the "sealed" panel meter:

I am in awe of Dieter - what a craftsman!

There was an article in "Electric Radio" a few years ago, about a TV-7
meter replacement using an LCD panel millivoltmeter, with the proper
resistors to match the original calibration. If you need it, I will
search.

Here's a write-up from the Texas Antique Radio Club for installing a
digital replacement:

If you can find another 200ua Phasotron meter, you may be able to adapt
that as outlined he http://www.n2xp.com/tv7tube.htm

Thanks for all the suggestions, guys. I will consider my options,
although, the digital meter looks easy and inexpensive.
