And I know there's more than a few of you here! 
Many moons ago, a friend gave me an old Marantz Model 2220 receiver. Looks like it was made in 1973 or '74 and packs a whopping 20 watts. It sits in the garage, and it still works pretty well. It has, near as I can tell, two problems. One is the volume control is all scratchy, and two is the balance control shaft is bent, and might be the cause of some of the scratchiness.
Can I get parts? Where?
I suspect some of you will suggest tuner cleaner or some such, but I'd really rather get new pots, rather than try to clean up the old ones, which I suspect are well past their prime based on the way they feel.
Not mine, but it looks just like this:

The scratchy volume knob is likely from dust, if you spin the knob a bunch (while it's off so it's not noisey) it should knock the dust out and work fine.

I've spun it a bunch. It doesn't change.
UNPLUG IT, open er up, get a corrosive controlling spray or something similar and clean it with that.
Parts would likely have to be fabbed.
Get some DeOxit spray from PartsExpress.
Be amazed.

I'm pretty hard to amaze. I'm not sure that removing the scratchiness would do it, but if that stuff can straighten the Balance knob shaft, I will truly be amazed!
So no parts, eh? They're just potentiometers.
It'll probably help/fix the volume control scratch.
But.... the balance shaft, nah.
I think there's still parts available for these, but they aren't cheap. This is one of those times you need to hop on ClubPolk or Audiokarma maybe and see if anyone has anything.
I'd try these folks, they probably have something close :

Wow! That's amazing! I need to pull it apart and put a meter on it and see if they have a replacement. I have bookmarked that site! Thanks!
