Just finished salvaging the fun stuff from a 1964 Baldwin model 54 organ. This is the 3rd one of these I have salvaged. the amp is powered by a quad of 6BQ5 tubes with another amp powering the spinning speaker thing with a pair of 6BQ5’s. The main amp was driving a pair of 12” CTS alnico speakers (the weird brown colored pair) and the spinner was a 12” Rola. The lower left chassis is some sort of percussion accompaniment and the smallest chassis is the reverb circuit. Check out the wood reverb unit with the monster size springs! I'm seeing maybe a clone of a Stangray in my future!
