Here are some “pre-repair” pictures of a Kalamazoo Model Two. The transformers date to 1965. It’s in nice shape, and just needs filter caps, a 3-prong cord, and a bit of cleaning. The tube line-up in these is a 6X4 rectifier, 6BQ5 (EL84) power, 12AX7 preamp, and 12AX7 tremolo. The old Raytheon tubes are still going strong!
