Well, I finished making the battery pack for my 41-81T, check the thread for that part of the project to see how I did it. Having made and double checked the battery to make ABSOLUTELY SURE all the pins were connected correctly on the socket, I then tested all the tubes in the radio. The 1A7G tested very good. It was a Sylvania tube, and may be a replacement. The other three tubes were all Philco and appear original. All three, the 1N5G, the 1H5G, and the 1A5G all tested marginal. I put the tubes back, and decided to go for it, see if the old girl had any life left in her as she is. I plugged in the battery, and turned on the radio. After just a few seconds I could hear a little crackle as I turned the volume control. I then tuned across the band and found that the radio received all the local stations just as it stands, despite the three weak tubes !
I will be taking out the chassis and replacing the two paper caps, and the one electrolytic next. Stay tuned for that adventure.
