my 4 tube battery set 39-70 has 5 tubes and an AC cord??
#16

In regard to David's mention of a Schematic...I expected there to be math involved but not ART! lol...and to answer the 35Z3 tube socket question there is no hardware holding it in place. The tube socket does not have any "ears" to screw it to the chassis so it is soldered directly to the chassis. I can't really see coverting it back to a battery set especially with what was involved in modifying this set. I'm sure that purists would disagree with me on this. I'm sure that we can all agree that when you're poor or can't find the parts you need you improvise and make do. I can repect that and even honor it. Seems more appropriate to keep it just like it is. My concern however is..after recapping and re-insulating the wires...being unfamilar with this set up...is it going to go up like a roman candle and set the house on fire???
