Always a good idea to pull the 9-160 & resolder it.
Also do the 9-155-01 CRT board. The main cap does go
bad but it causes width then hum bars. If the
9-160 is bad ( 98%) beyond simple checks I would just
replace it. Gotta remember that design is in the top 3
for complexity along with RCA SCR & Sonys with 2 SG613's
which its the worse. In the end there are only 2 different
ones, 9-160-05 & 9-160-06. They replace all other numbers.
Didnt sell many of them. IIRC they were just a little more
than regular tuners. Maybe they were trying something to get
away with a cheap alternative to tuners but didnt get
a good response. Selectors were reliable. I only remember
changing one for a dial cord.
