**** HELP NEEDED WITH A ASTRON POWER SUPPLY ****
 

I have a RS-20m power supply and would like to put variable voltage on it, up
front with a knob. The variable small three leg pot thats undreneath the board
now reads 1k 909. I'm just a novice at this and need help. I believe I need
to take the small pot off and run three wires where it was connected on the
board to the variable pot that will be mounted to the front but what size pot
do I need in its place. Any help would be appericated. Email address is
