[Collins] VFO Schematics

[Vernon Van Zandt]

Greetings.

Anyone here happen to have the schematics for a Collins 310C
VFO/exciter, and wouldn't mind sharing them?  

Also, sometime ago there was a question posted regarding a mod that
allows the VFO to be used for 160 meter operation.  Something along the
lines of adding a buffer amp circuit...?  Can anyone can shed some light
on this, or even details (schematic maybe?) on how it is connected,
etc..?

(Sorry about the cross-post, but my question would be verbatim on both
anyway...)

Many thanks,
