Orgatron I

via John:

"I've had this thing for several years-- found it at a pawn shop-- but never thought to look it up. It's an old monophonic electronic organ. It says "Orgatron I" on the front. There are four switches: 1. Power 2. Vibrato (On/Off) 3. Volume (Slider) 4. Voice (Flute, Reed, Brass, Horn). The last switch appears to be some sort of preset variable filter. It would be awesome to mod it to be continuous, but that's beyond me, and I wouldn't want to open it up. It will run on 6 C batteries, but also has a standard AC power adapter plug similar to the Casio SK-1. Anyone know more info on this? All I could find was this:" "Here is a vintage Orgatron I which is a battery operated organ or you can use an AC adapter for electricity instead of batteries. It takes 6 “C” batteries which are not included. This organ comes in the original box and there are 5 music folio’s included. They have 8 sheets of music with a song on each side and there is quite a large variety of music. The first folio also has the instruction sheet and it is dated ©1973 GTR Products, Inc.

Here is a list of some of the songs available to play on this organ. Little Brown Jug, Pop Goes the Weasel, Old Dan Tucker, Ten Little Indians, Skip to My Lou, Red Roses For a Blue Lady, A Hot Time in the Old Town, Twinkle, Twinkle Little Star, Greensleeves, Fascination, Animal Fair, This Old Man, with some religious songs along with a few Christmas and so many more... It measures 15 ½” long x 8” wide x 2” tall."

Update via pea in the comments: "this is the same thing as a GE Tote-a-Tune"
