    A search here will reveal your answers. For the scratchy volume you'll want some deoxit. Do a search on threads with deoxit in the title and you'll find one with step by step instructions. I'd also search lamp replacements and see if there is a thread about doing them on your unit.

    Thank you I wasn't able to find much information on my unit. Do you think I should replace the caps in my unit? Cause it hasn't been serviced in a long time

    Do you think it was an awesome score finding a vintage stereo receiver?

    I know nothing about MCS stuff - other than it was sold by JC Penney for a time. And my younger brother had one for a few years. If you aren't hearing any unusual buzzing or crackling noises it might be fine. If you want to do something with it replacing the power supply caps is always a good place to start.

    But I think that is due to the volume

    Also the front lights on the faceplate sometimes don't turn on

    Does evrything but the lights still work? If so it may just be a bad solder joint in the lighting circuit, a flakey bulb going out or a faulty switch. Give it a few taps on top if the lights are out and see if they flicker or come on.

    Yes everything but the lights work. I went to an antique shop and I talked to the owner about my receiver and he gave me his service repair man number.

    Some of the MCS units were made by NEC.

    Sounds like a little deoxit and some solder touch up will get you going again.
    I'd say it's definitely a great score finding a nice receiver anywhere but especially if it was going to be thrown away and you can give it some more life.
    I'd do some reading on how to clean it up. There are lots of opinions and methods. I generally use windex and then a quick detailing wax on the outside of my stuff. The inside it really depends on how dirty it is.

    As far as recapping, I'd listen to it a while and see how you like it. If it's acting up you can always do some reading and go through it at a later date. Typically you'd do more than caps so a bit of reading and maybe some practice on a junky VCR from the thrift store would be in order before jumping into something you like.

    Welcome to the abyss of audio repair. without adding a bunch of bs.. .. do you have any idea of repairing or testing experience ? I write this because the unit itself might be best left alone and traded. :D
