I have a number of tube testers. My workhorse is my Simpson 305...

I have several others, among them a Sylvania type 620 which is my only tester which will test the FM-1000 tube used in the Philco 48-482.

I also use a Superior Instruments TV-11 as a backup...

and also an EICO model 628 as another backup, and a Precision Tube Master Series 10-12 which I have yet to restore.
In this hobby one cannot have enough tube testers. They go along with the hundreds of rubes I have collected over the years, Last year I spent many nights testing a few hundred of them, ones which I had not tested in at least 40 years, if at all. They were ones I took from old sets I scrapped years ago, or bought by the big box full at flea markets years ago. They are now all in proper individual boxes and labeled. I amassed them in the days before the internet when many types were already becoming hard to get, and I wanted to have a supply I could fall back on if needed. Because of that, I now have types like WD-11 and 01A, 26, 27, 35 and so on that are becoming more and more expensive.
