(Almost) Final Touches

I can't get to my VTVM right now (long story so I'll spare you), but a quick alignment by ear brought up the high end of the 70 nicely. While it picks up the 600 kc signal from the signal generator very well, on antenna the low end seems...well...very low.

Oh, and now it requires the tube shield to be in place to prevent the unit from squealing (oscillating). Which, I think, is a good thing.

Rob, I would be most interested in reading more details on how you went about bending tuning cap plates to achieve more uniform response across the AM band.
