[Collins] 32S-3 driver and PA tube screen resistors

Greetings,

I am just trying to fill a couple more squares in my notes on component evolution. All of the 32S-3 manuals call for  R41 at V7 pins 8 and 3 to be 22k Ohms, 2 Watt. I am wondering if the 1973 or 1975 32S-3A manuals show that it was changed to 12k Ohm, one or two Watt?

Similarly, all of the 32S-3 manuals call for R113 feeding the PA screens to be 1750 Ohm, 3 Watt. Do the later 32S-3 manuals show that it might have been changed back to 1200 Ohms as it was in the 32S-1?

Thanks for any information on this question.

73, Bob, KF6BC
