Thanks Bob. The step by step approach with the explanation of your reasoning based upon your observations is really interesting. Great content as usual.
I could smell the solder while you did the pins. My mentor told me not to breathe it as much as possible. Good thing I mostly switched to silver solder when it came out. Nice job on the pins, it ain't going anywhere...
Bob, I highly recommend Loctite 574 it's an anaerobic flange sealant that sets like concrete and sticks like shit to a blanket. If left exposed for a few minutes it thickens up nicely and when it hardens it sets a pale orange colour. It's the only thing I've seen that's remotely like the original stuff. Give it a go!
I have had so many problems with high value carbon comp resistors over the years, I automatically replace them with metal film resistors. Additionally, high value carbon resistors generate noise, which can sometimes degrade circuit performance. The wiggly picture may be due to the AGC partially clipping sync pulses. After replacing all the usual parts for the restoration, the problem may be gone.

Osram Sylvania BC-1631 Basing Cement, I suspect that it is no longer available.
@9:26 He’s got Red Foreman forehead. Ha!
Though it wasn't shown on video, I take it that something like acetic acid free RTV was used for the base.
Listen again at the 2 minute mark.
