Hello!! I was studying the Hallicrafters S38D schematic the avc line is a negative voltage. My question is: How are the negative voltages produced in the chassis? Thank You!! Daniel

Just a quick comment. Radio picks up a signal. It's amplified. The detector then rectifies it to generate a negative AVC voltage. Stronger a signal greater negative AVC voltage.
