Hi John
with all the talk about remote control...I was just thinking how much I like the "feel" of the big brass knob I made on the volume switch, and wondering if I were so inclined, what would it take to have a second volume control switch to manipulate the sender control. so rather push buttons on a hand set, have the knob and rotary switch remotely placed, sending the command to the preamp's rotary switch. I realize extra expense for two volume switches...but just curious
