Vintage McIntosh MR71 Tube FM Stereo Tuner - Parts or Repair

Description

Wish this was in better condition but this is how I found it.
The unit powers on and the front lights turn on and from what I can tell all tubes (except for 2 of them) glow orange.
I only powered this unit because previous owner said he has powered it on recently. I know that if it hadn't been powered on in a while it is best to power it slowly, with a variac.
One of the tubes is broken - in the 4th picture of this listing it is one of the smaller tubes at the top of the picture, one white a white-ish looking top.
The tube right next to the broken tube, again the other with the white-ish looking top, may also be out, it does not glow when powered on.
All other tubes look to be original, from what I can see on them they do have the McIntosh logo print on them.
There's a lot of tarnish and pitting, and some rust spots. Actually a lot - see pictures.
The front panel glass is free of scratches or cracks.
The knobs are in fairly good shape, not pitted or overly scratched.
I took the bottom cover off, because I know it is important to see everything on these things, and it looks clean. Old, but clean. No noticeable issues.
When powered on, and again the lights turn on, I do not get sound out of either outputs. Perhaps only a little bit of static but that's it. No radio station come in.
This is being sold in AS-IS condition - for parts or repair. Please inspect the pictures carefully so see what you're buying.
If you have questions, ask. I generally respond promptly.
I've shipped similar product before so I know how to pack these. The exposed glass tubes will be removed, bagged and labeled for secure shipping. All other components will be protected from movement to prevent damage. Front glass will also be protected from damage to breakage. Not my first rodeo with these.
Will ship via FedEx. Package will be insured for final sale value and signature will be required for delivery.
There will be no returns, no refund, no partial refunds after the sale.
- I will be listing a couple of other McIntosh items (a preamp and an amp) within the next few days so keep an eye out. These two other items are in similar rough condition.....sadly
