[SignalOne] Short video presentation of my CX7

[Bob Sullivan]

Peter,

I’m so pleased that my ‘old’ Signal/One newsletters and articles are still providing information to help keep these unique rigs operational! 1977 seems like yesterday. HI

Nicely done on those repairs!

73, Bob

Replacing the capacitor was an easy fix and the radio sounds great again. The new cap fit perfectly in the old paper roll that held the original cap so you can't spot a new part added. While at it, I added a fuse in the screen line as suggested to protect the final 8072 tube.
