My next project, dad's Philco 40-81

I used 8 9 V cells in a Motorola portable that used the same arrangement. It works fine although I think 7 for 63 V would have been OK too. Others will chime in but I don't think the voltage level here is that important. You can snap the 9V batteries together using their own connectors and make something very close to the size of the original 67.5 V battery.
