I just finished aligning it using an HP 3336A in sweep mode and a Tek 465 scope. Totally unnecessary but I wanted to give it a try. The marker works by modulating the brightness so it goes from dim to bright right at the desired frequency. I set it to 460 kHz and discovered the set was peaked close to 480.

A little trimmer cap tweaking and I got it back where it should be. Radio is playing great now Icon_smile
