Hi Dave, I've emaied the schematic for your Freed NR5. It's not as clear as I'd like but about normal for the vintage. It doesn't indicate the tubes on the schematic but the A supply voltage is 6 volts for all tubes, it will use 01A tubes in all positions. Later models used 01A's with a 71A output tube but your set uses the same C- bias voltage for the driver and output tube, the 71A would require a higher bias voltage and your set is a couple of years too old for the 71A anyway. They will all be 01A's. Good Luck, Don Black.
: Looking for copy of schematic for Freed Eisemann model NR5. Have one w/o tubes.. need to find list of the 5 tubes. Email Please..
