Re: Cretinous idea - The combined volume pot and mains SW.
Most televisions from the 1960's and 1970's used combined on/off volume controls. It did not seem to cause to many problems with hum pickup even on some of the televisions that had a decent size and quality speaker fitted.
From the servicing point of view they could be a pain to change when the on off switch failed.
