Sorry for the long winded post, but here it is..
Since the discussion is regarding distortion and frequency
response, I would like to share some experience I have had with
improving the fidelity of otherwise mundane audio power
amplifers. Although some of the technicques presented may require
I have found that a good rule of thumb for using linear
amplifiers on AM without burning up the tubes is the max. carrier
output from the linear should be no more than half the total CCS
dissipaton of the tubes. Case in point the pair of 6146's at
20-25W carrier, etc.

Hi Don,
The envelope full of 260 info and your flier arrived safely today. I sure do
appreciate the time and effort that went into making copies and getting them
in the mail. I have several 260s and swear by them when working with
boatanchors.
I recently picked up a 360 which looks the same

I received the envelope today with the Simpson 260 info. - Thanks for
sending it along. I looked it over and will place it in my "Simpson" file
for future reference. You can never have too much equipment information!
I did check out your "Want" list to see if I could help yo
Again, It would be an S1 signal above a s9/30db level noise - a barely
perceivable difference.
You would have to go from 100 to ~ 6,400 watts to get an S3 signal above
that noise level.

Exactly.
However, if you intend to employ significant audio clipping as a means
of peak control and loudness enhancement, the low freq response should
ideally extend well below that to better accommodate the flat topped
waveforms without substantial elevation of their peak level caused by
the tilt
When the interference is also at 30 over S9(even if it's static crashes) a
36 dB over signal using the 400 watts helps. First put up the best ant...
Then crank-it with juice!!!

No matter what the spin, 100 to 400 watts is only 1 s-unit
and barely perceptible at the receiver.
A 30db/s9 signal is from a good antenna not from
100 or 400 watts.

It probably was Bill's voice and audio that drove the QRM away.
