Zenith K731 - New Line Cord, Brief Power Up & UL Captive Knobs

Wrapping up the repairs on Bob's Zenith K731 from the early 60s. A new line cord and polarized plug is installed followed by a brief power up and performance test. In addition, a quick look and discussion on UL "captive" Knobs. Thanks to Bret Frohwein for his insight and feedback on this subject. Thanks for watching and following my channel on vintage radio repair.
