Hi,

After some repair I had a working NTP177-400 meter.
It worked nicely until...
I dropped it while building it in a nice housing.

Now the bar graph is broken. The gas has left the tube.
So no more light.

Does anybody know where I can buy, reasonably priced, such a tube so I can repair the meter and
enjoy the looks of the plasma bars again.

Jef
