I have a TV7/U,it use a bulb as a fuse.It is important to use the correct type: 81,(6,5V,1,02A;6,6W).

I have found that types 81 & 47 (pilot lamp) bulbs are used in Gottlieb flippers, so it is easy to buy them at sellers  of flippers spares parts  (in France there is one on Ebay.fr,he sell box of 10  at very reasonnable price)

On the picture,the; yellow bulb is original (GE81),he silver one is a 81 for flipper (exactly similar to original).

I have tested the spares,they runs as originals ones.Using european cars 6V bulbs is also a solution,but they do not complies exactly (6V; 5W ),flippers spares are preferables.

TV-7 military tube testers are appreciated and widely used because of their versatility, ruggedness and simple operation. Unfortunately the meter just gives arbitrary values, from 0 to 120, and data tables indicate the minimum acceptable value for each tube.

But the arbitrary values of the meter can be easily converted to the actual mutual conductance Gm, expressed in micromhos, using the table below.

 

Intermediate values can be readily calculated by linear interpolation.

The table comes from the TM 11-6625-274-12 manual, covering models TV-7/U, TV-7/AU, TV-7/BU and TV-7/DU. Probably it should also apply to TV-7/CU.
