Hi Charles and everyone. 
I could not read the text of your post. This happens sometimes on
Hammond Zeni posts where the text from the post seems to be deleted and
only the title and some other  superfluous non post related  text
appears .
 
If you are asking about boosting the volume level of the bass pedals of
a B3   , C3 , A100 , RT3 , D100 etc organ   , then one simple way to
achieve this is by  disconnecting the 10 ohms  grounding resistor that
is connected on to the pedal click filter inductor coil that is easily
visible connected  on to the middle of the back side of the upper manual
, between  the oiling  instruction  sticker and the preset panel when
looking in  from the back side of the organ. 
 
Disconnecting the 10 ohms grounding resistor  causes a noticeable
increase in the  bass response of the 16 ft pedal drawbar.
Shorting out the click filter  inductor coil  produces a more bass
guitar like pedals sound  with more key click  on the 16 ft  pedal
drawbar.
 
On my 1962 C3 organ  this pedal click filter has two coils with brown
enamelled wire and the 10 ohms grounding resistor is mounted on  the
inductor coil.
On my 1965 C3 organ that I bought last Friday ,  the inductor coil is
covered with a rectangular  aluminium cover and the 10 ohms grounding
resistor is connected on to a tag strip  next to the right side of the
covered inductor coil.
All the best.
Kon .
