RCA model P46725SK, chassis on back says PTK169PFA, but on chassis
inside cabinet says CTC169PF. Original problem was cracked focus/screen
block (though I see that someone has replaced the HV splitter block as
well before I got my hands on it.) I posted earlier regarding the
missing little board on the HV splitter block, but have since learned
that apparently they didn't all have that little board - this is the
first one I've seen that didn't.

The remaining problem is the pincushion. This chassis has a pincushion
board off of the main chassis that I have checked the components on
several times (all tested OK) and even replaced Q4850 on it since I
read one post where someone had it test good when it was in fact bad.
The picture is very good except for a classic pincushion (actually
bowed out at top and bottom) and none of the controls have any effect
on it. I keep reading about CR4402, C4401 and C4402, but I don't see
them on the board anywhere (though I'm certain that they're there and
probably marked differently) and all the components around the HOT that
I suspected may have been them seem OK. Can you get that pincushion
board as an entire assembly somewhere? Is the consensus that the pin
board is the problem?

Thanks in advance for any ideas/previous experiences with this.
