The CTC86 was a rare chassis to see. Always looked
good. Its the last RCA modular set. The 220K resistors
were also a common fail on the newer replacement "unitized"
chassis along with what looks like a vert out transistor
but RCA called it something else. The unitized kept us busy
with FBT's, audio, bridges & vert problems. The '86 seemed
to be very reliable but I thnks they built few of them.
