Well Jack
You left us hanging......did you get it fixed or resolve any of the problems? Triode amplifiers can sometimes be challenging to get settled down, but their simplicity makes them attractive to build. Hope you are having success with your rig.
My apologies to all. I seem to have forgotten about this thread and never read any of the responses until just now. Shame on me!
I think the problem is that I had two threads by the same name discussing different problems and I forgot to check the notify box.
Furthermore, I gave up in disgust and went back to 40 meters with it. Where I have no such problems but had a modulation problem that I just resolved tonight but can't find anyone to talk to on 40 to confirm it.
I am waiting to go back to 80 after the hamfest on Saturday at which I hope to get some needed parts. I had the feeling it might be too low Q in the grid tank but now after reading all these ideas, I think I will make trying some of them my project for tomorrow.
I have to go through the numbers for the power supply cap but I did add a 2 mf to the rectifier side which now makes it a cap input. The only effect it had was to raise the voltage about 200 volts. I have a limited supply of these old oil filled caps so they are on my list for the fest. I would like to run it at the higher voltage.
Anyway, I will keep you posted when I learn something,
Thanks,
