Hi All;
Jerry I would have to dis-agree with you..
As, You know I have a Philco 34, which is a Farm-Battery set.. And mine has more voltages than His Set does.. And I am verry Happy with my Set..
Granted, I have had to build my own Power Supply.. But, that is just part of the fun !! I used two Power One Regulated Power Supplies, one for my 2.0 Volt Filament supply and another one which was a +12 volt and a -12 volt, which thru a couple of Resistor dividers I got my +3 volts and my -3 and -7.5 volts.. Then using a Transformer that had two primaries for 120 volts AC, I made one the new secondary and after rectifying it I had my +135 Volts.. The twin Primaries were for making it either 120 VAC or 240 AC depending on how you hooked them together.. I have edited this and changed Switcher to Regulated..
THANK YOU Marty
