Hi, Bob
That is very simple mod. Changing some RC timing constant on AGC and 
one cap. change(the audio coupling cap, in the audio amp section).
I found out the values does not have to be exact.
In my case, I changed the value of R440 to 470 Ohm, C280 to 0.66 mF,
C300 to 1.39 mF. Also if your R85 is 10K Ohm, change it to 4.3 K Ohm to
increase the sidetone level.
That's it.

P.S. My old 765 has all the mod. that I know of. In every day use.
