I am in the process of getting my fathers old Philco 48-141 up an running which is a batter powered raido. The specs on this site show the above battery pack. http://www.nostalgiaair.org/Resources/624/M0013624.htm . However, they don't seem to me made anymore 
I had it running before using a very simple DC regulator I built using a transformer, a bunch of old zener diodes and some batteries. However, I am now wanting a more permanant solution using an actual battery.
From the schmatics, it looks like I need taps with 85, 5 and 1.5 volts. While the 5 and 1.5 are simple, the 85 my need a power inverter to boost the voltage off of a standard 12v battery. Has anyone ever done this before? If so, where could I find the schematics.
I am also i need of the battery plug and socket. The AC cord is original but I the plug is broken and I would like to replace it. I also need the socket for the battery pack that I would like to put into the case.
The final goal is to make this chargable using the AC adaptor or a 12V DC source from a car or a solar array....Yes, I know I am crazy for this but who else has a solar powered tube radio My father use to run it off of their windmill that was also use to pump their water.
