RCA Television with Built-In Closed Captioning

[RobtWB]

Those CTC 175 -177 chassis are remarkable for 2 things - the crappy onboard tuner / board solder points and the tactile switches that fail frequently.
I've accumulated 2 of them, both 177AM2's. Both have had the tuner resoldering done, and 1 has had its switches replaced.
Having said that, for some reason beyond my comprehension, both sets I have produce excellent pictures, and both have thousands of hours of playtime.
Certainly NOT one of Thompson/RCA's better designs.
