Your "debate" maybe Rich.
The "subject" is of interest to many.
The 6M amps I build use a regular Pi-Network, same as an HF amp. The only
difference is that more of the Tune C is in the tube than at 10M.
Since the parasitic frequencies of the 572B is close to 6M it becomes
harder to suppress without excessive loss in the suppressor.
In an HF amplifier, this is not the case, and

Best ever that I have tried and not fried. And as I said the idea was
used on an HF 5KW amp back at National Radio. Since the engineers knew
enough to use it they must have had references to consult....... Handy
