: nonflammable resistor.

: fusible resistor.

 

: internal component.

 

: panel designation or adjustment for repair.

 

All variable and adjustable resistors have characteristic curve B, unless otherwise noted.

All voltages are in Volts.

Readings are taken with a 10Mohm digital mutimeter.

Readings are taken with a color bar input signal.

Voltage variations may be noted due to normal production tolerences.
