I can't seem to find DeOxit locally here in Canada. I have a co-worker that says an electronics store near his place might have some, otherwise I'll order, I might have found canadian supplier that would ship to here.
In the meanwhile, I have purchased another contact cleaner, thinking It'll be a start. It does work wonder on the volume pot.
But I realised the PB/BC/SW/FM switch is a beast on its own!
It is not a single casing with 4 contacts, but rather a mecanism, leading to a rod that includes a series of sets of switches.
from that top knob:

to that shaft:

here's one end inside the chassis:

another end of the chassis:

In essence, there's like 4 sets of switches in there. I fail to see why pushing the knob gets better contact under those conditions. I wonder if it might be related to a wire I changed, leading to a lesser quality connection? I'll have to give it a try, after I change my e-caps. After cleaning and letting evaporate for about an hour, the result wasn't as expected and all is still as it was. "better luck next time"
On a better note, I received my caps!

Overtime aside, I might have time to do that before easter.
So I have 22mF 450V as a replacement for the 20mF & 25mF e-caps.
