I have removed the dial scale, the same way that Greg removed his - by turning the tuning condenser about halfway open, removing the four push pins that held the scale in place, and then carefully slipping it off the pointer.
Greg, how did you fasten your new dial scale to your T7-5? All four of the push pins that held my dial scale in place were rusted, and all four broke when I removed them.
I've hit the pointer with more PB Blaster where it is fastened to the tuning condenser shaft. With the dial scale out of the way, it is now easier to get PB Blaster into the point where pointer meets tuning condenser shaft.
I also removed and disassembled the ball bearing tuning assembly. It is made very much like Philco radios with two-speed tuning, and came apart the same way. It is soaking in naptha now to degrease everything. I have the knobs soaking in Evapo-Rust as the metal springs inside the knobs are badly rusted.
I attempted to rebuild the little top hat 6H6 tube and install two 1N34A diodes. Everything went well until I discovered that the top of the tube no longer fits properly onto the base. I could have sworn that there would be enough room for the diodes inside there...
