[Collins] 32S-3A Manual

[Glen Zook]

The only difference between a 32S-3 and a 32S-3A, made at the same time, is the additional crystal board and the switch to go between the 2-crystal board and the nomenclature on the front bezel.  Otherwise, the transmitters are exactly the same.  Now, for units not manufactured at the same time, then there can be differences in the circuitry.

In fact, sometimes, a 32S-3 transmitter would be almost complete, even complete, and a 32S-3A was needed to fill an order.  The 32S-3 would then have the additional parts added making it a 32S-3A.

That May 1, 1969 is the latest at CCA and at mods.dk. I have that in 
print. I also found a 32S-3A manual in my library shelves 2nd edition 
dated 1 December, 1975. Something like that might exist on ebay. I 
haven't looked but my google search turned up some ebay hits that I 
didn't check.

The 32S-3A could have significant circuit changes from the 32S-3 but 
probably only the added crystal board. I haven't compared the manuals.
