As I recall, the problem is that "Z" previously stated that, according to the characteristic curves, a 3-500Z(?) flows __mA of grid current when the grid-cathode potential is negative __V. According

It does not appear in your signature. for Zebediah? Because you are a human just like most of the rest of us.

Gidday Z, Keep postin mate,callsigns dont matter, I don't post, just like to read an learn...just finnished me first amp an picking up tips for me next one...so keep em coming. Cookie zl4ad

Yeah thats far far too much, he must have had some dirt on his glasses when he did that measurement. I have a T-4XC on the shelf, one of these days I will measure it. 73 Jim SM2EKM -------------------

Those tests where at full power, with quite a bit ALC pulled, also quite a bit of processing. One can say that both radios was "forced" a bit, did also use an audio RF clipper with the KWM2. This is a

Sounds like someone needs to review his basic tube theory. Specifically, look up "contact potential bias". Now, for the experiment. Lay tube on bench. Any tube, as long as it works. Apply specified

chortle Charles Thomas Rauch, Jr. It can't be Rauch because he knows that the grid has to be positive with respect to the cathode in order for grid-current to flow. R L Measures, AG6K, 805.386.3734

Definitely Not. So why do you hide your name? He also looks down on those who do not agree with his technical missteps. > > R L Measures, AG6K, 805.386.3734 r@..., , rlm@..., www.somis.org

Yahoogroups allows the originator of a posting to delete it. Or the moderator can. I don't fundamentally like that - once posted, a posting ought stay as a matter of record. That's usually with very
