OK, Ed and anyone else who needs them.
There are 5 separate PDF articles on these mods. Since I am not sure which mods have
been attempted on your receivers, I will send them all. I suspect the one that is of most
importance to you is the one labeled, Ultimate_Super_Pro. BTW that article was not written
by Lee, but Reed in 1957 for CQ magazine and is 9 pages long.
Lee wrote one on adding/converting the Super-Pro for SSB, and Geissler wrote another
article on modifying the Super-Pro.
Lee also wrote an article on modifying the AR-88 for "improved performance". I am not
including that one.
Lastly, the service bulletin from Hammarlund (which I cannot find directly now, but will
continue to look for it) is mentioned in detail in a Hints and Kinks. The capacitor suggested
is a 3.3 pfd TC cap with as high a negative temperature coefficient as possible. N-750 will
work, but an N-1500 was suggested by Hammarlund.
I will include all these PDFs to anyone who wishes to have them.
