What's up, Doc ? (sorry, I couldn't resist) I restored a 41-81T and had to build a new battery for it. Fortunately, it had its old battery still inside, and the outer sleeve of that battery, and the connector were still in excellent condition, which made it much simpler. Still, the technique is much the same for making any replacement battery pack, except you will have to make your own outside box for it. Here is a link to the thread I posted about making a battery pack for my radio. I hope it is of help to you... http://philcoradio.com/phorum/showthread.php?tid=10728 . ALSO, AND IMPORTANT, I checked the schematic for your radio on Nostalgia Air. It says the B voltage should be 80V. The connector of your set looks the exact same as mine, and I suspect it used the same battery. Look down farther in the link I posted, and you will see a discussion of this too. Best of luck with your project, and do keep us posted.
