Ok, first things first I guess. I was able to do the first three alignments provided that my 100 yr old sig generator still works and that I was using it correctly...
I turned up the volume full blast, started with the 1st tuner, adjusted it slowly till I saw the voltage (analog) going up then back down, and I went back to the voltage peak for the first three adjustments and the speaker got louder with each adjustment so I feel good about that.
But, it went downhill after that. Once I unhooked the signal generator lead from the 6A7 and replaced the grid cap, I hooked the sig gen lead up to the antenna clip on the back of the radio. That's where (I think) the instructions say to hook it up. There was no voltage shift when I adjusted the OSC; H.F” (#15) or the other two the Detector: (#11) and the ANT; H.F.” (#8 ) the three screws on top of the tuner.
Nothing happened.
Maybe I have the signal generator on the wrong settings? There are some dials on the bottom, not sure what the one on the far left or far right should be set at?
Also, and maybe more importantly it says to turn the dial to the same channel (1400, 1500, 600 etc.) as the signal generator, but my dial only goes up to 150...is the dial's 150 really 1500?
Here is a short video of my radio dial and the WWII signal generator I'm using.
