Mondial: I will try taking the #44 tube out altogether tonight and see if I still get short wave. Right now, it's only in the socket and it's grid cap wire connected to the #36 tube. What's the easiest way to tell if the RF stage is oscillating, and would that indicate the SW reception is caused by the 44 stage, as you mentioned?
Skyscraper: Thanks for confirming the winding for the OSC for me. I actually cut a strip of clear plastic from a page protector and wrapped it around the coil, securing it with scotch tape before I began winding the coil. I will try injecting a 260khz signal to the grids of the 44 and 36 tubes and see if that helps. I have an RF signal generator but not an oscilloscope. Thanks, too for the RF Coil connections.
All of this is very helpful information and I appreciate you both sticking with me as I fight my way though
