I would try a triac from earlier CC2 chassis its probably the same.
Seen NOS triacs on e-bay. They get subbed to a kit 800-###, I
dont remember all the number.
I wouldnt recap unless a problem. There is a 10mfd 315V on the
back edge by the FBT that always goes. I would remove the 9-160
& go over it for cold joints, there ARE some !
For the RF check the ant cable. Also the tuner plugs get cold joints.
On the IF board 9-151-# ? there is an AGC delay control.
Last check the CRT socket 9-155-01 for cold joints especially under
the white resistor pack & socket itself.
