If I did the math right a 24 ohm 3 watt resistor will be just right for the crt shunt resistor. Tom.J

So what is being said is I would be able to use the 14atp4 provided I put the resistor across the heater. I looked at the size of both tubes and if I didn't miss anything it looks the same maybe a 1/6 inch different which I should be able to make that up if that's the case. The heater voltage would be enough 6.3 v aside from the 8 volts the 14atp4 requires.
