You are aware this is a surface mount miniture transistor mounted on the bottom
of the board? It's a standard NPN surface mount transistor, comes 5 in a pack
available from any RCA distributer. It takes a small iron and steady hand to
replace.

Chassis is CTC 169AJ
Problem is most likely Horizontal Sync Buffer transistor - Q4402, listed
in the manual as "Stock Number 215495"

Anyone know how to find specs on this, what to replace it with, or where
to get an exact replacement?
