I have a 4019U that plays very well, but the stereo balance control does not work. After checking all the switch contacts, tubes, capacitors, most of the resistors .Not being familiar with this model, I need some help getting this radio to work properlly.Would someone please help me?   Thank you Ross W. Hoff

Hello Ross,

as I see it the radio has no stereo encoder. Stereo works only for devices connected via PU and the Stereo A button is pressed (M6: 17-18 shorted) . Only then the rotating contact of the blance potentiometer is grounded and thus has a function.

Regards

Giovanni
