I found a Traynor YRM-1 schematic. It uses both side of a 12ax7 to drive the pan (cap coupled). The is 4FB2B1B which is a Long 16" 2 spring, with 1,475 ohm input and 2,250 ohm output, med delay, input grounded, output insulated, horizontal mount. But the cool part is? They have note saying "DC resistance of input & output is approximately 180 ohm". It would be nice to know other impedance reading for quick info on what the pan is...
