Seems a little low, should be around 15 volts. Check resistor #43, the large wire wound unit. Off the top of my head I don't recall the values and can't read it on my poor copy of the schematic, sorry. The 42 tube is the one tube that consumes the most current in the radio so the bias needs to be correct or it will upset the whole set.
