You still dont get it yet do you Bill? The coil must be self resonant at/near the parasitic frequency. However the Q is way too high and the exact parasitic frequency is not rock stable and varies wi
ORIGINAL MESSAGE: REPLY: Remember, reactance is lossless. Reactance alone can not "quench" energy, in the sense of suppressing or absorbing it. Only resistance can do that. Think of the coil and resi
ORIGINAL MESSAGE: REPLY: You asked which commercial amps were burning up suppressor resistors (implying there weren't any) and I gave you four recent examples. Caught with your electronic pants down,
ORIGINAL MESSAGE: REPLY: In all my years as a ham, this is the first time I have heard anyone say that a VHF parasitic suppressor coil MUST be self-resonant. Where did you get that from? Did you thin
As reactance is lossless that is just how it quenches. Quench does not mean to absorb, it means to put out, stop, or even prevent. IOW it prevents the parasitic from getting started. Another way of p
ORIGINAL MESSAGE: REPLY: We're getting pretty heavily into semantics here. For purposes of this discussion, I'd say any of those words are ok. 73, Bill W6WRT _________________________________________

Right on Roger, you get a gold star but I guess that Bill just cant absorb this....His mind is in quench mode............ Carl KM1H _______________________________________________ Amps mailing list A
Thank you Bill, I see that I lead you rather well into displaying your true ability or lack therof. I absolutely knew that you would mention well used vintage amps as your only recourse. Carl KM1H __
And perhaps some misunderstandings as well. There is no such thing as a pure inductance. EVERY real inductor has stray R and C. EVERY real inductor has a self resonance. EVERY real inductor has loss.
ORIGINAL MESSAGE: REPLY: I'd rather hear it from you directly, Carl. Why MUST the suppressor coil be self resonant? Let's hear it in your own words. 73, Bill W6WRT ___________________________________

ORIGINAL MESSAGE: REPLY: Was that your push-pull 2A3s with raw AC on the plates I heard the other day? Those were the good old days, weren't they? :-) 73, Bill W6WRT _________________________________

Whats the matter Bill, youre not an ARRL member or are you just a knee knocker afraid to do some research on your own? You just may learn something. Carl KM1H ________________________________________
No, my pre 1930 derived rig runs PP 211's with DC on the filaments and regulated 1000VDC on the plates. Its worked close to 100 countries on 80CW. Several on here have heard it and report it sounds g
Youre such a big sissy. I gave enough info that even a brand new no coder or CBer can find it. Maybe one of your camp followers qualifies and will play coolie for you. Carl KM1H Back from La Belle Pr
