In many of the early color sets (as well as b & w) for that matter, it was imperative to replace any shielding removed for any service operation.

Failure to replace shielding after service could cause a miriad of problems.

Even something as simple as a broken ground connection of the rf cable between the rf output and the if section could cause very weird problems if one wasn't aware of the result of such failures.

Make sure when you are restoring your oldies that care is taken to replace tube shields as well as shields around sensitive areas.

My number one rule of serving was, if the engineers put it there, it must be there for a reason!

Happy restorations.
