These are dual triodes, often used in audio applications. I have found three. The first is a very premium 12AX7. It is a Telefunken with flat plates. It tests 150/150% on a Hickcock 600 tube tester. Tubes and More sells these for almost $300, which is ridiculous. Buy this one for only $75. The second is an RCA with ribbed plates. It also tests 150/150%. Tubes and More sells these for only $170. Buy this one for only $50. The last is a KenRad with ribbed plates. It tests at 125/125%. Buy it for only $40. Buy all three for $155. . 12AU7 Dual Triode Vacuum Tubes: I have an OEM styrofoam box that originally held 100 tubes. They are 5963 tubes, which is the heavy duty industrial version of a 12AU7 -- a very popular dual triode tube, often used in audio applications. These are obviously NOS (New, Old Stock) tubes, so I only tested a couple and they test over 125%. Since I have so many, I will sell for an exceptionally good price. They are normally about $10 each. Buy one for $5, five for $4 each, or ten or more for only $3 each. . Sweep Tubes: I have a 6JE6/6LQ6 Sweep tube available. It is a Sylvania. It tests at 115%, so should be good for full output power. Only $40. . Zenith 6LB6 My tube tester will not test it, so condition is unknown. $20 . Buy both of the above for $50. . Compactron Tubes: I found some 6D10 and 6AV11 compactron tubes, which are very close to "unobtanium" these days. All have been tested, and test at least 110% with most being higher. These are often used in a variety of Heath equipment, as well as other ham gear. 6D10 Two available. $18 each. 6AV11 Four available. Two are marked "New". The other two test the same. $10 each. Buy all six of the above for only $65. . I also have many other accessories available such as many different types of microphones, HTs, VHF and UHF rigs, HF and VHF/UHF antennas, connectors, miscellaneous accessories, etc. Just too many to list here. Please e-mail your requests. . Prices do not include shipping from Florida. Thanks. 73, Ken, W8EK Ken Simpson E-mail to W8EK at FLHam.net or W8EK at arrl.net Voice Phone (352) 732-8400 . .
