Today finished resistors (Mouser came) and tone control.
The tone control in 96 is the same as in all similar radios: 95, 111, 112 and even 90.
Unlike the metal version, this one does not allow to pull or push the caps compartment out, so it had to be picked out after some heating. Not bad at all.
I was able to reuse the wires that went from the contacts to the caps.
The tone ctl was dirty. I took it apart, as I knew I would have to clean the contacts.
Then pried out the caps.
Cleaned the case and the contacts
Then prepared the assembly from three caps: 15nF, and 2x10nF.
As I said, I was able to re-use the wiring. I lined the bottom with fish paper. Even though the case is backelite and there is no fear of the case shorting things out. Just felt right.
Made a cap from fishpaper, to keep hot glue from damaging film caps. Yes, I know, some folks here stated this is safe to pot them directly, but then it costs me nothing and puts my mind to ease. I also used eraser on my pencil to clean the contacts a bit more, as somehow my usual method, IPA, did not clean all of the deposits. Then washed with IPA again, as rubber, if not washed off silver, will blacken it over long term due to the sulfur present in it.
Then I potted.
This is the Tone Control
And installed it back.
