Got it today. Even though the model prefix indicates it's from '69, all the tubes have '67 date codes on them. I guess they were trying to use up old parts stock on these later tube radios. Unfortunately, the audio output tube socket crumbled to pieces when I removed the audio output tube. This radio appears to have a lot of hours on it and since the audio output tube is the hottest tube in the radio, I'm not surprised that it fell apart.
Here's the video I made of the radio:
