Ctc-16

messed about with the convergence, got it all pretty good except for the blue horz on the bottom, I just cant get it up (pls no pun) the pot is turned all the way and it just runs out of adjustment.

Vert looks good from sides to center, and horz is fine from center up, just the blue begining about 2/3s down.

I did check the sams the replacement diode are 1N536's

could those effect the max range of adjustment?

50v .75mA silicon, so looks like any of the 1n4 family should be ok,

Ah, that convergence board brings back foul memories. I nearly lost my mind fussing with the board on my first CTC-11. Replaced selenium rectifer with diodes, replaced caps, replaced a couple of pots. Those controls are laughably cheap and not easy to find. Some kind soul donated one, or I'd still be cussing over bad convergence.

I spent hours playing with convergence on that set. On my second CTC-11, convergence took about six minutes, and it looks better than the first ever will. Go figure.
