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

reading about this had me on pins and needles!i have done in excess of 50 cataract removals and never an issue.lucky me,no more.after reading this and dougs story,i think its time to stop.i have a couple nice roundie crt spares and will use them.i had good luck with spraying penetrating oil in the the edge of the safety glass and letting it run before i heat the tube face.never use high heat.it is time consuming but the end result........!i have pushed my luck one time too many.never again!
