[Collins] 32S-1 unknown mod

[Bill Riches]

Just obtained a clean 32s-1 that has a mod in it that I have not seen.  I
have not fired up the unit yet.  Pin 6 of v2 plate of BFO  osc is connected
to a 100 k pot thru a 51 pf cap.  The wiper of the pot is connected to p7 of
V4 first mixer through a 100 pf cap in series with a 22k resistor.  The 100
k pot is mounted on the same type of add-on bracket that is used for the vox
time const control mod. The knob on this control is identical to the other
knobs on the other three controls.  Workmanship is first class.  Is this a
Collins mod?  What is it for?  Inquiring mimes want to know!
