[Collins] W2VCZ and Mills 75A4 Mods

[Dr. Gerald N. Johnson]

Some comments, without details are at:
http://www.radioworks.com/Hamshack/75A4.html Apparently Howard Mills, 
W3HM had many mods he liked.
http://www.collinsradio.org/html/a-line380.html lists address and e-mail 
for W3HM so maybe he can document his mods.

http://mailman.listserve.com/pipermail/collins/2005-July/msg00171.html
catalogs some of the mods by both W2VCZ and W3HM without details.

http://forums.qrz.com/showthread.php?173551-Collins75A4-A has a long 
list of sources about mods without specifically mentioning W2VCZ or 
W3HM. I've not checked the lists of mods.

With the many mods by Collins it could be hard to determine which mods 
were new and which ones were actually bringing an early A4 to the latest 
Collins circuits.

http://www.w7ekb.com/glowbugs/rx/receivers.htm has links to files about 
one VCZ mixer mod. Refers to articles but without citations of where 
published. 
http://mailman.listserve.com/pipermail/collins/2007-July/msg00265.html 
points at Electric Radio as the place published.
