I bought this organ in May 2002, after looking at it at the previous owner's home in Huntington Park, California. This organ was designed and built by Gulbransen in 1961, and was manufactured at least through 1964, when a piano option was added. This organ has the piano option, which means it was built in 1964 or later. This is the organ with the two Leslie speakers that came with it: The organ at this point is still on the dolly because one of the Leslie cables was damaged when we brought the organ home, so I wanted to be able to move the organ to connect up the cables when the repair parts for the cable arrive. The Leslie cabinets were designed by Don Leslie expressly for this organ in what he characterized at one point as his finest achievement. Leslie was a devoted Theatre Organ enthusiast--his goal was to reproduce accurately the sound of a theatre pipe organ through his speaker designs. Here's a description of the two Leslie cabinets shown in the picture: Size: 29 x 21 x 41 inches (except for position and number of louvers, it looks just like a 122) Speakers: 1 - Rotosonic Drum (under the woofer), single speed, single speaker 1 - 15" woofer 3 - 6 x 9" stationary (in top section) Amp: 4 channel x 16 watts Also has an "Isomonic" unit Size: 29 x 21 x 41 inches (except for position and number of louvers, it looks just like a 122) Speakers: 1 - Rotosonic Drum, fast/slow speeds, 2 - 6 x 9 speakers 1 - Rotosonic Drum, single speed, 2 - 6 x 9 speakers 2 - Stationary 6 x 9 speakers Amp: 4 channel x 16 watts Also has an "Isomonic" unit These are pictures of the two speaker cabinets: Leslie 103   Leslie 102 Yesterday I figured out how to open up the top of the organ and I took some more pictures -- this time of the inside of the organ console. The first picture is shows the circuitry for the tab stops (the curved circuit board on the left in the picture) and some of the electronics associated with the upper manual: The next picture shows both manuals and the tab stops with the wood panels removed to show the circuit boards and some of the circuitry for the upper manual. Next we have a view with the upper manual raised. We can see the keyswitch linkages for the lower manual, the audio preamplifier and power supply for the entire organ, the keyswitch wiring for the upper manual, and the switches and wiring for the reverb, percussion, and other effects: This picture shows the key linkages for part of the lower manual: Another view of the tow manuals with the upper manual raised: This view of the under side of the upper manual shows the rear part of the key channels with the linkages to the keyswitches, and the keyswitch assembly at the bottom. In the upper manual, there are 12 key contacts per key. If you count the pins coming out of each key's contact strip at the bottom of the picture, you'll see there are 12 on each one. The last picture shows some of the wiring for the tab stop circuit board and the keyswitch assemblies:
