Resistief netsnoer (Techniek Radio/TV)

Ik lees net in een schema : "R13 is a special tapped line cord and the scale lamps are shunted across one section of it"

When the receiver is operated from A.C. mains, HT current is supplied by the half wave rectifying valve 35Z4GT.Smoothing by resistor 2K7 and 2x32uF capacitors.
The HT supply voltage for the 12A4 valve is obtained directly from rectifier cathode.
