Adding A supply to this B Battery Eliminator
#21

Thanks for all of the suggestions. I have all of the components needed now for the schematic Terry drew up and will attempt to build that in the not to distant future. As for now, I'm still trying to get the radio itself to function as it should, temporarily using ten 9V batteries for the B and a 1.5V flashlight battery for the A. The batteries power the radio fine for testing, but long term because of the load for the filament circuit I can see how it will go through a lot of flashlight batteries. May start another thread on the chassis restoration of the radio itself if it continues to misbehave. Already found the primary of the OSC coil was open.

Quick question for Terry....on the LM317T, is there a designated IN and OUT pin, or can either of the two outer pins be used as in?
