[Milsurplus] RAL Audio Gain Control

[Richard Brunner]

If anyone wants to add an audio gain control to the RAL it requires no 
mutilation and is simple.  Pull the dc power switch back and wrap it in 
plastic so it can't short anything, and mount the 100k pot in its place. 
  Run two small shielded wires through the hole in the chassis nearly 
directly above it, and wire in place of R-119, the 6D6 grid leak 
resistor.  the rotor of course goes to the 6D6 grid.  It looks like good 
ergonomic design...
