RE: ALC Adjustment Procedure

notone-am, your system sounds very good to me. I may employ a similar process to my quad mrf-150 amp.
One can get uo to 800W out of 4 mrf-150's(push pull combinerless)
You are using a comparator type adjustment.
You seem to have only 2 states. Amplify with no adjustment.(no ALC OR ANYTYPE OF CORRECTIVE SIGNAL FEED
BACK.)
If there is any type of distortion, then and only then you cut the drive until distortion is below the kimit you set on your
comparator.
Hmmmmmm....I guess with your PSUEDO ALC scheme a minimum of attact and instant off is interesting to my app.
73 tnx mike

Sorry, Alan, but I must point out to Philip that the
Dipole Fan is used for cooling the antenna when you
over drive your amplifier. You can dress him up, but
you just can't take him anywhere! :-P
Alan, your article reminds me of all of the mistakes that I ever made with an amplifier. The worst was believing that you
could not over drive a pair of
4-400As, grounded grid. I thought I had read everything before I built my "Moose", but all I can do
is apologize to all of those nice hams that I saturated with "splatter" until I learned better.
Fortunately, my one and only amplifier was that one
and I outlived it 33 years ago. Maybe some day when I
am a bit older and a bit more of a curmudgen I will build another amp. For now I am happy to run barefoot
and spreading Athlete's Foot spores every where! :-D
Enjoyed the article. The ham bands should be a bit better for your advice and wisdom.
(No, Philip, a WISDOM is not an off center fed antenna!) Sigh!
