For grins, I connected a 6AQ5 to a constant current power supply set to 600ma and measured the voltage drop across the heater. The heater voltage stabilized at about 10.5 volts! This is indeed really pushing it for a 6.3 volt tube... I suggest that proper 5AQ5 be ordered as well.

OK well I also noticed that the previous owner of this TV had installed a 6BU8 in place of a 3BU8 tube in the TV I'm guessing that should also be replaced with the proper tube as well?
