Check the note that I've outlined in yellow in the attached schematic.
However, as a youngster, I remember that most, if not all the power switches were indeed integrated into the volume control.
For you old timers: is that how you remember things too?
Anyways, a little trivia; I built almost an identical circuit as shown. But I couldn't get a hold of 35C5 tubes, whereas the 50C5 were fairly common.
Therefore i used the 50C5 and removed the 35W4 rectifier, and substituted it with a selenium rectifier.
That way the total filament voltage matched the household voltage.
