The QBL 5/3500 does not work in GG, believe me. Could it be because it is not an Eimac tube... ? The world seems to spin around Eimac. Peter/SM2CEW -- FAQ on WWW: http://www.contesting.com/ampsfaq.ht

In my case, f. Wanted to use a tube that did not work in GG, without having to build the screen/grid supplies. Plus the fact that the tube is easy to drive with the DAF circuit, in my case 35W in giv

Well, it has been tried, with no success. Could be that then the tubes were used and had little emission left as they were pulls from FM transmitters. A new tube might work. But 170W i a 'lotta' driv

Larry, To me this indicates that you equal high power with having a poor signal, = bad IMD. People can be LOUD and sound very good too you know.... if the amp is designed for the job and the exciter
