    It does seem like there is a bad connection in the light circuit. Maybe a bad solder joint or maybe a loose connector. You might try a new thread asking about AK techs in your area. We have some good ones here.

    Sure, why not. Just get a quote first. Then decide if its worth it to you.

    Definitely use some deoxit in the control pots. If you've been inside other electronics you shouldn't have too much trouble inside this. There's no surface mount anything and there should be a decent amount of room to work. There's also no HV to worry about like in TVs though mains voltage can definitely be dangerous.
    With only some of the bulbs working you either have some burned bulbs or a bad connection somewhere which shouldn't be too hard to track down if you're comfortable. Even if you bring it to a shop it shouldn't be too much labor time to diag and fix.

    There's rust on the circuit board. I have one bad cap too. When I found it my Autistic brother plugged it in and hooked up small TV speakers into the speaker terminals when I told him not to plug it in and it was raining when I found it. So he probably blew a Cap out

    Be sure to clean any speaker selector and stereo/mono switches too.

    You can use something like deoxit on the board to clean the corrosion. Spray a little on and use an old toothbrush to clean the rust.
    Inspect the solder joints for corrosion and if you find any I would remove the old solder and resolder the joint.
