Also, some of those bakelite block caps may have an integral resistor in there and not accounting for this can cause many problems or burnout irreplaceable components and kill a tube or take out the power transformer.
Replace them all. Including all the filter caps and the metal can caps and tone control potted caps.
Also check ALL resistors for out of tolerance values (+/-20% of nominal value).
This is WAY too good a set to give it short schrift in restoration.
Convince your customer he's flirting with the prospect of "yet again" having it restored in the very near future or cause a fire if not restored properly, if he intends to be playing it a lot and keep it plugged in.!!
I'd hate to see a 16 turn into a Shelf Queen. It may work for a while and then the non-replaced parts will go out and your customer will call you all names in the book.
Please do it right the first time.
