Hi all,
I'm a new member here, but i've spent many hours reading this forum over the years. Great source for info, thanks!
I'm starting the process of rebuilding/converting a vintage Raytheon RC11 tube broadcast console into a 9x2 tube mixer. It originally is a "dual" mono console, each channel has a switch to send the audio to the program or the monitor amp, or off (center position). I want to replace these switches with a NewYorkDave style panpot, to convert the program/monitor amps to "left/right". I am not sure what impedance/resistor values I should be shooting for. Each mic preamp has a plate to line transformer feeding a 500ohm daven attenuator, and then a 470ohm mix resistor feeding the mix bus. Input for the program/monitor amps are 500ohm line to grid transformers.
Any ideas on the best value for the panpots? I would like to remove the 470ohm mix resistors (and switches) and replace them with the NYD panpot circuit.
Attached is a schematic for the RC11.
Thanks!!!
Tyler
