Vintage Receiver score - Sony STR-6036A

Woot, I just scored an old receiver! It's a Sony STR-6036A. Not for the main system, but the vintage look is kinda cool for somewhere else in the house. My wife spotted it on FB buy-nothing group locally, what an enabler!

Here are some pics, attached.

I'm in the process of doing simple external cleanup. I'm going to have to fix the broken slats on the vent on top. I bought some oak 1/4 in. by 1 to cut down to the right size, and tried to choose a stain that looked like the right color. Info I could find online called the finish 'light walnut' but Home Depot only had much darker walnut. I hope I can match the finish, but fear I won't be able to.

Knobs and switches are all dirty. I saw some guy spraying Deoxit in them on youtube and figure I'll do the same. But I do have this question: one source said don't use anything that leaves a residue to clean the tuning capacitor (use what, then?), another guy said use Deoxit, just spray it out with compressed air afterword. What does the vintage restoration brain trust say? I have Deoxit and an air compressor, that part's NP.

Otherwise, it seems to work. I played a bit of FM through it, but haven't done more than that, I'll have to finish going through it. This is ~ 1972 vintage, so part of me says all the electrolytics should be replaced. Another part of me says that if it ain't busted, don't risk making it busted. I'm mostly here for the speakers, I know a bit about the electronics but I'm probably not going too deep into the guts here.

Chime in if you have experience with one of these units, or know what I should be doing with mine!
