Hi Mark,
No,? the text is correct. The paragraph is relating to the RF Gain control, not the volume control. We don't touch the wiper of the volume control. The wiper of the RF Gain control is connected to the RF input of the AGC attenuator array through C3. That is properly shown in the drawing (the blue wire) and on the schematic.
The graphics staph does not get paid this month due to their regrettable errors but the editorial staph gets their usual salary. This time.
Thanks Mark. Keeps me sharp. I may re-word that and will try to be clearer in the future.
73,
Don?
