Marantz 2238 receiver rebuild

Ya...spring isn't here yet so I need more to do. My son's Marantz is going to get a recap.

It's mainly just dusty! I don't see much for corrosion anywhere.

    She's done and it still works! Nothing major - all caps replaced and rebiased.

    Looks like there's room in there for a motorized remote controlled volume pot. :*

    For the wizards out there... Was there a machine that did the wire wrap? That is a seriously secure connection. I had no idea...

    Or sell it to me as is. Seriously.

    No sale on this one. Belongs to my son.

    But I am watching for one to operate on

    Nice project! Marantz are pretty easy to work on. I couldn’t stop noticing the cloth covered wire on the main filters. Are you into guitar amp as well? I used the same type on tweed deluxe build :)

    I've got a couple of spools of the stuff. It's got a rubber coating, then cloth. I like it on the bottlehead kits I build. It's a fairly heavy gauge and works well in the PS section. Easy to strip - easy to form...

    Well... that would just take all the fun out of this now wouldn't it! If I make a career out of this that might come in handy. The wire is almost worthless after unwinding it (winding a round wire over a square peg really puts some weak spots in it) so I check length before removal just in case.

    I recapped an old, really pretty old Pioneer receiver for a friend a few years ago. I owed him a favor and it turned out fine, except I saw when I had it opened up that the dial cord was about to go, and I wasn't going to touch it. He had to take it to some old guy up near Ann Arbor to get it replaced. It was a lot of money, but he did it amazingly quickly, my friend watched him do it and said it was like watching a machine.
