When I was in high school, I read an article about "All American Five" 5 tube radios. The tube filaments were in series and were connected (directly!) to the AC power.

A friend had an electric bass guitar and when we were looking into the amplifier one day I noticed that the circuit was an AA5 with the RF section removed. The circuit board looked to be an AA5 board without the RF parts populated. There were resistors (much larger than 1/2 watt) soldered across the points where the RF tube filaments would have connected.
