With the repair bench ready, I am starting to revamp my test equipment. 1st on the list is the Precise 111M tube tester. This one is a little different than most I have seen. It must be a later version, since it has sockets for the newer compactron type tubes. Since I will be working on TV's as much as radios, this one appealed to me since it has sockets going back to the 4 pin tubes as well. No adapter needed! The major drawback (to me) is that there are more knobs to set than for a Hickok. But, it does look like a more thorough tester too, so it has its place.
I have gone through the calibration procedure with my other 111, but this one is a little different. I don't have the manual or much of any updated tube charts. Bama has manuals for the older versions, but so far, I haven't had any success in finding info on this "M" model. It is the same as a Radio Shack (Realistic) 113. Any help in this area would be greatly appreciated.
This tester appears to have very little, if any use at all on it. There is absolutely NO wear anywhere on it! It has never even had screws put into the cabinet! I kind of wonder if it ever worked right. My first test revealed a 'bouncy' meter, and inability to set the 'line'. It does test tubes, but I am sure it's off. My 1st step is to recap, then attempt a calibration. This one also has a transistor tester. It could complicate things, since I don't have any assembly/calibration instructions. Any info, insight, advice or comments welcome.
