RCA CTC146 chassis: Any known issues?

[radiotvnut]

This is a hot chassis set and I'd advise against adding any sort of external A/V inputs. You'd be better off connecting the set to an RF modulator.

This was an entry level chassis, introduced in about '88 and replaced in about '92 by the infamous CTC17x series chassis with the EEPROM and "on board" tuner issues. I don't recall any problems that stand out and if if works, use it and enjoy it until it stops working.

Using the Sams for CTC146A / B
U1001 is A29-1101-01A OEM #193082
Video output is pin 47 goes to L3205 Problem is audio is still there.
The audio is filtered out by CF2301 & video fed to Q2302 vid amp.
After that it goes back into U1001 pin 49 for processing.

Ah, it's a hot chassis set? I had no idea, I assumed by 1989 hot chassis sets weren't even a thing any more.

Always assume the chassis is HOT & use an isolation transformer.
Even isolated sets can have several grounds & a switching power supply
is hot on the primary. Its also common for a set to get hit by
lightning & the RF input goes hot.
