Honestly, I do not think (in your lifetime), you will ever find a more Beautiful, Iconic, Rare and WORKING piece of equipment! Look at the pictures and look at the thumb wheel for the roll chart, there is ZERO wear; the whole tester looks like it was never used, or maybe once or twice. This testers condition deserved some electrical restoration to get it back to working condition, so I did that for. There was no calibration procedure in the manual (original and included), so I simply used my Lab quality 6L6 calibration tube to verify this testers function; ALL was "right on" as expected. This Rare tester will test all older tubes, like popular 2A3 and W.E. 300A/B audio tubes. It has a modern 7 pin tube socket but not a 9 pin. FYI, with this testers patch cord scheme, you only need to have a tubes base connections to test almost ANY tube. As you can see from the pictures, the production tag shows a date of Dec. 11, 1944. ALL of the patch cords and power cord, are in great soft condition. Some spares are included. I thought, at first, the main Gm meter needle was sticking at low end of scale, but when actually testing a tube the needle moves up and back down to zero, just like it should. This tester is 70 years old, so I must list it: AS PICTURED/AS IS. ONLY USA bidding. Shipping weight is about 45 lbs. THANKS, 73's.
