I picked up this (second) nice little six-tube wood Arvin 6640A way back in 2005 for $95.00.
It was partly recapped and as you can see the cabinet was in pretty good condition.
When I dug into it however, I found quite a few spots with considerable rust on the chassis. I didn't want to rip everything off though, so I removed all the rust I could by getting in between all the components or under IF cans and what not with wire brushes and/or Emory cloth.
When it looked presentable enough I recapped anything that hadn't been done and adjusted and aligned everything. It really sounds quite nice now and lots of sensitivity all across the entire AM band.
I sprayed the entire chassis top and bottom with gloss lacquer to prevent any future rusting.
As far as the cabinet goes there were a lot of little nicks and tiny scratches and dings here and there but it certainly did not require a full strip... so I cleaned it all up and wiped it down. Then I re-sprayed two more coats of clear gloss lacquer on it, which floated and blended everything together to bring the finish right back up to a quality look.
I then used 0000 steel wool to take it down a bit to a satin-type finish and when done I used Butchers wax for a final polishing.
I think it now has a real nice almost-original look to it. What do you guys think?

But I do try hard to pay attention to small details.
Refinishing is not really as difficult as I used think it might be, a few years back, when I had no woodworking experience at all.
