1960s Kalamazoo (Gibson) Model 2 7w 1x10" Tube Amp Combo

While it's not fancy, it sure sounds good and growly! This Champ-like little guy would make a great harmonica or bluesy amp and it's even got tremolo onboard. I have not checked the transformer date stamps yet, but the owner thinks it's a '61 or '62.

It's been entirely serviced as evidenced by a number of replaced capacitors under the hood and a 3-prong power cord. It appears original otherwise. When dimed the speaker does a little bit of "fart-out," but them's the breaks (and the advantage if you're into old-school sounds) with this style of cone.

You can hear what it sounds like in the video -- I do bring it all the way up. If one wanted a more-controlled sound a simple speaker swap with something modern like a Weber would do the trick.
