CTC187 pincussion

[James Sweet]

I've got a CTC187 with pincussion distortion, sides are bowed in. Seems
to be a fairly common problem which is usually cured by changing a
capacitor. Problem is I'm not sure where to get parts anymore? I have
the RCA part numbers but I haven't had the usual luck with Google,
there's so much noise these days. Where's a good place to order this
stuff anymore?

If you can't see bloated caps at C4407 or 4403 then you may not even
need parts. Usually on 187's the pincushion problem is normally a high
resistance pad where the pin damper diode and C4407 connect. Rather
large pad that you need to scrape down and reflow solder there. 9 times
out of 10 that was the fix.
