Oh yeah, they are moving. Not rocket fast - needed the package to come from Mouser, then other things....
Today rebuilt the tin cans and the tone control as planned, the tone control seems to be exact same part as in 90, so I already knew what is there and how to do it, simply looking at the photos I took from the previous one.

One of the tone control caps was simply open. The other two were 25nF instead of 15nF and 10nF.
The slider is black - really black. I clean what I could with alcohol, then sprayed with Deoxit and will dry overnight before potting.
This will be it, then the power up.

Did you also have the wires really brittle?
When I was soldering the big cap can back in place some wires would crack; I dressed them in heatshrink. I don't think there is any danger but although I did encounter this brittleness before I never saw that many stiff wires.
