I think I might get one of those combo multimeter/basic oscilloscopes eventually either way, but good to know it's not a must. So I'll look for a cheap signal generator perhaps once I feel up to doing alignment.

The wires are a bit long since they cross most of the width of the chassis given the switch is in back and the #46 cap is near the front. Shielding couldn't hurt. Should the ground from the audio jack (or where the radio in gets switched to ground) go through a resistor, or straight to chassis? It seems like every discussion I find about adding in an aux jack suggests different resistor values for left and right for the stereo-to-mono conversion, while some suggest resistors on the ground and some do not.

Parts for the antenna coupler arrived too but I have the chassis out so I can glue some veneer and I took the long wire down since ants were coming in along it when the weather turned nice. I'll get to it eventually.
