V10 is the noise rectifier. It is a 6H6 type.
When making pin-to-ground resistance measurements, make SURE the radio is configured like this. To locate tubes, see this.
Resistance measurements made with Simpson 260.
"Open" or "no pin" means the tube does not use the pin but it might have been used as a junction for other components.
