Paul Harker sent me this URL that has the details of his restoration of a Kalamazoo Model 2 Amp. The model 1 and 2 are the same circuit except for the tremelo.The Kalamazoo amps are famous for two things. First is wonderful tone. It is one of the best sounding amps for harp around. You can get a good range of effects from dirty to warm and smooth out of one amp. The other thing that is known for is not being very loud. In fact it is what you would call a quiet amp. So if you decide to get a Kalamazoo amp, be warned that you will have to mic it to the PA in order to be heard over the guitars.
Kalamzoo amps are very common. I have two dead ones in the cellar that I have to get around to fixing. You can pick them up on eBay very cheaply because guitar players generally want a louder amp.
Paul put a bit of work into his K and it looks pretty good considering that it was a junker to start with.
