--cut-- --cut-- I guess I'm kind of in that group of new participants but was also a member for a short while back when Mr. Measures was still active on the list. Things were so intense between he an
That's gotta be the "Classic Line Of The Week" mate. I mean what is a parasitic suppressor? What is any parasitic suppressor? Is it not something that "attacks the symptom and not the problem"? Wheth
To me this list has had (since the aforementioned problems) the lowest noise ratio of about any list I've been on. I may have a lot of time, but I've found out more about tubes and amps on here than
Interestingly when I asked W6MTF at Eimac for some advice regarding parasitic suppression when I was first building my 3CX3000 amp a decade or so ago, he immediately advised me not to bother with sup

All good points Roger. I remember a saying from decades ago that a few should consider on here and elsewhere when expecting others to take the time to try and help with a problem. "It is not a good
ORIGINAL MESSAGE: REPLY: Rich's claims and statements have been analyzed to a fare-thee-well by others as well as himself and there is no voodoo involved. On the contrary, the naysayers have offered
The concept of a "suppressor" is to suppress the parasitic from even starting. The Q of the strap, wire, coil, has nothing to do with the design. This is where the voodo starts. The coil of the suppr
ORIGINAL MESSAGE: REPLY: For a tube to oscillate, the circuit Q has to be high enough on both the anode and grid circuits, enough so the gain is one or more and the phase of the fed-back power is cor

ORIGINAL MESSAGE: REPLY: This is the crux of the argument presented by the anit-Measures naysayers. Measures claims, and I agree, that a nichrome wire coil has lower Q than a copper one, and especial
ORIGINAL MESSAGE: REPLY: I'd say not. Neutralization can be done with very high Q and high impedance in both anode and grid circuits and involves deliberately feeding out-of-phase energy from anode b

** No argument so far and especially so when skin effect is taken ** So what? We are discussing a HF amp where its the goal to transfer the maximum RF to the load and not heat up things unecessarily.

A play on words for students while maintaining the engineering method. Its actually by Horowitz and Hill. The term "art" was part of many textbooks, I guess it was done to impress the young and sell
