The original TV-2(not for TV-7 or TV-10) percent quality meters-brand new for sale. All TV-2 models use the same 100uA, 250 ohm meter. These were in sealed packages when I got them. I opened them to take photos. These measure 100uA full scale, 250 ohms internal resistance with a Fluke digital meter. Most 100uA FS meters have above 500 ohms internal resistance but TV-2 percent quality meter has only 250 ohms. This makes these meters very difficult to manufacture and expensive. The last photo show the internal resistance measurements of 250ohms. I have seen TV-2s that always indicate low test value on percent quality meter. These were caused by re-faced meter with higher than 250 ohm resistance. Replacing the percent quality meter with the original(100uA, 250 ohm) one cured the problem. These will be sent by express and insured mail. www.alltubetesters.com sells non-original TV-2 meter at $365 + $15 shipping. My price is $290 including shipping to anywhere in the world from Korea. I have a few of these available for sale. I was lucky to find these. No return will be accepted unless I made mistake in above statement. **Word of Caution** Do not attempt to measure internal resistance by using automatic or low ohm ranges of multimeter. I use above 20K ohm range. Using lower ranges may cause excessive current and the meter can be permanently damaged. Before installing this meter, make sure the TV-2 is in good condition. If you install this meter into a malfunctioning one, the meter can be damaged again. I cannot accept return of this meter.
