- Hi to all I'm new to the list but have read the archives and want to build an amp. The guys at the club said that I should try a 4-1000 tube because they are "very forgiving". I have read rich's web

- To: <amps@contesting.com> Hi Rich, The tube might forgive you, but you might not forgive it! 4-1000A's are notoriously unstable at high anode voltages, and getting a bit scarce. You will need about 5

- I have a 4-1000A amp here that was a homebrew I bought. I have been fighting it for the last 6 or 8 months plus....It's almost done now. I haven't found the tube to be any more unstable at 6 KV. The

- To: <amps@contesting.com> Hi Jon, Despite your questions about how to get your 4-1000 to work right on ten meters, you seem to suddenly now not have problems with performance. They absolutely are les

- To: <amps@contesting.com> yea, verily. More volts means more gain. Is not vhf suppression anti-resonant? There is undoubtedly no way to make the anode-circuit non-resonant. Greatly increased losses h

- To: <amps@contesting.com> Hi Jon, Most tetrodes are that way. Some fellow keeps trying to sell Ameritron on a G2DAF circuit, claiming it has "good and fully acceptable performance". He finally delive

- Yes, true. However, all the "specs" I've seen both from Eimac and several editions of W6SAI's book say the IM at 4000 V is -34 dB and at 5000 V it doesn't even list IM specs. I suppose that's cause

- To: <amps@contesting.com> What Eimac data sheet lists IMD for grounded grid 4-1000A's? The tough part is driving the PA with a clean signal. That takes two exciters with very linear output stages dri
