Digging into the CTC-9

[Phil Nelson]

I hope your experience with the convergence board is easier than mine with a CTC-11. Replacing the selenium rectifier that had fallen into pieces made a difference. Shotgunning other board components, including some pots, did not lead to miracle improvements. Eventually, I decided I could get edge convergence purty good, but not perfect. I chose the set of compromises that I liked best, and called it done
