Will sell for $50.00 plus shipping OK U guys without any test equipment ... here is a toob tester for 50 bucks.... Brian didn't put any pictures of it on his web site... so ask if it covers the 4,5,6,7,8 pin old style tubes ... I am betting it does.. I believe it does, but what you need to ask is whether it is a real transconductance tester or just a mutual conductance tester. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

....I'm sure you meant "real transconductance tester or just an
emission tester" in the sentence below....I believe that "Transconductance" and "Mutual Conductance" are synonomous WRT tube testers! IIRC, the Knight 600B is an emission type tester. 73, Leo On 6 Oct 2003 15:49:05 -0400, (Scott Dorsey) wrote: snip I believe it does, but what you need to ask is whether it is a real transconductance tester or just a mutual conductance tester. --scott |

These are much more useful than, say, a TV7 because you can own it now and not have to save money for years. If a person would like to use a Hickok but never buys one and has to guess as to tubes, how are they ahead of the game? I'm absolutely certain many of you would say it's MUCH better that they NEVER buy a tester their entire lives if they can't afford a high end Hickok. Yeah, everything else is a toy, uh huh- and the TV7 doesn't even give a direct reading IIRC but requires math each time ! That's a bit like my hippie friends here who walk to work because their 1959 VW Transporter is perpetually in the shop or a ditch (they can't bear to be seen driving a less than cool car). John H. |

Actually, some of the cheap Hickok units are real transconductance testers, and some of them do show up for next to nothing now and then. They aren't any TV7, but they sure beat out the drugstore testers. Some of the emission testers are no better than drugstore testers, and they have a tendency to indicate perfectly good tubes are bad, or vice-versa. This can be extremely frustrating if you ask me. They'll find open filaments and poor emission, but other problems (especially on beam power tubes) do not show up on them. When you're paying some of the bloody insane prices on power tubes thes days, a good tube tester can pay for itself in short order in the tubes you don't throw out even though they are fine, and in the tubes you don't have to keep around for substition testing. --scott -- "C'est un Nagra.
