Tonight I did a complete alignment on the 56X5. I guess somebody with nothing better to do began to play with visible screws because things were WAY off. First I set the IF, had to reset both adjustments on both IF transformers, A LOT. Went back and forth a few times and got them peaked at 455KC. Then I went on with the rest of the alignment and had MAJOR adjustments at every stage, but finally got it all dialed in. It receives well on both the standard AM broadcast band and shortwave, despite having a marginal 12SQ7 first detector/oscillator tube. I even was able to pick up WWV at 10 MC using just my 10 foot indoor test antenna, not to mention quite a number of other shortwave stations in both the 9 - 10 MC and the 11 - 12 MC international broadcast bands. It will be fun to see how this radio performs once I have it all finished, have installed a new 12SQ7, and test it on my outdoor antenna.
