V14

V14 is one of the 6V6 push pull audio output tubes.

When making pin-to-ground resistance measurements, make SURE the radio is configured like this. To locate tubes, see this.

Early Radio Resistance Measurements

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.
