Help with tube tester
I have a chance to buy a bunch of electronic equipment from an out of business electronic store. I would do so because it includes tubes and some tube testers. It also includes some old recievers, preamps etc. He wnats to sell the stuff all as one lot. I am new to tubes but learning and would like to pick up a tester. The guy says he has a Supreme Radio Diagnometer Master Series #301 by Supreme Instruments in a nice oak box and also a Supreme Model #35 tester. Anyone know anything about these, such as possible price and value to me so that I can test the 6922, 7308 E88cc type tubes that my preamp uses? I know enough to know that I should go over and see the stuff and take down some model numbers and tube numbers to have a better idea of what has got. Any help even pointing me in the correct direction would be of great help. Thanks

I purchased a B&K 606 on ebay and used it for the first time tonight. What a sweet little unit. Very easy to understand and use. Only two things I am not sure of. One is it says to wait for the tube to warm up. I assume that means about a minute - but I know some feel that tubes take 30 minutes to fully warm. Anyone know how long to warm before performing a test? Second is in the middle of the socket bank, there is an 6 inch wire with a cap sticking out. There is no reference in the instructions to what that is for. Anyone know? Thanks Joe |

I do not think the Supreme Model #35 will test 6DJ8/6922/7308 tubes. Still might be worth owning though especially if it is in decent shape. Made in 1935. Supreme Tube Testers |
