Non working Philco P-841A tube radio battery, manufactured to provide "A" battery voltages of 7.5 and 9v and "B" battery voltage of 90v. Size is 9 1/2" x 4.5" x 2.5" amd weighs about 4 lbs, obviously not working. This battery can be "rebuilt" using 9v "transistor" radio batteries and "C" batteries to power vintage tube radios. Case is in decent shape except for one side which is rather scoffed up (see photo). I restored one of these for a Philco 49-607 radio (the one with the roll top) which I sold here on eBay.
