Saw some strange old sets today

I have an RCA Super TV set that has a similar looking chassis, in that the boards are solder mounted to the chassis with the foil side mostly inaccessable. I did a recap, but I just did the expedient of just soldering the new caps onto the leads of the old cap that were snipped with enough length to J hook onto. You can't see the top side of the boards inside the set anyway, as they face inwards to the back of the CRT.

On my set I had a dirty volume control pot, that would sometimes let the wiper contact float. RCA used the pot as the grid resistor on the audio output tube, and it got rather unhappy when the wiper went open circuit. So I connected a 470K resistor to ground to protect the tube. I was able to get at the required foil lands on the circuit board for this.
