After repairing a SWTPC Tiger .01 (207/A) from the 70's I want to set the bias correctly. I have a copy of the assembly manual and have attached a copy of the schematic and also the bias adjust procedure. However, I question whether the bias procedure is correct. First of all it says that bias current should be set to 40 millivolts. I think they meant to say 40 milliamps. But even if this is what was meant it goes on to say to adjust for 15 mV between test points M and N. Wouldn't that product an idling current of 19.23 mA? If 40mA is the goal, wouldn't the voltage between M & N have to be adjusted to 31.2 mV? Or am I wrong? Thanks for any advice.
