Re: Enough!
Steve et al, Without taking a stand on either side of the argument I will say this... Bob, KR4DA, started this group to give us a place to have amplifier discussions without senseless censorship due

Re: Ham Radio Magazine
Hsu, Sorry but I don't. My Ham Radio on CD only goes up to 1976. I have been meaning to buy the second CD from ARRL with the rest of the issues but just have never done it. 73 David

Re: 8170 AMP
80 thru 10 actually... but I ran it mostly on 40 meters in the combat zone. It was able to produce a 40dB over S-9 signal on 40 meters from Tucson, AZ into Somis, CA... Amazing... -S Phil Clements

Re: 8170 AMP
Hi Greg, To be honest, I don't recall ever running this thing on 10 or 15, although the grid circuit did resonate nicely. I used the AG6K circuit which incorporates a trifilar input transformer and a

Re: 8170 AMP
Steve, I am impressed! What a fine piece of workmanship. Please add a pix of the schematic. I assume it is a 20m through 10m tank circuit? (((73))) Phil Clements, K5PC

Re: grid driven tetrode
Correct. AB1 means the grid is never driven into positive region. Sure, it sounds strange to say the maximum grid potential is 0 volts, but it's true. For a pentode, the minimum anode potential can

Re: grid driven tetrode
So Rick, Do I assume you never want to drive the grid 1 positive or let the plate voltage swing below the screen for cleanest output? Any feel for the output power limit for say a 4CX3000A holding
