Philips Philicorda GM752/01B Electronic Organ

The Philicorda GM752 followed the GM751, the first model in the GM series from 1965, in 1967, with a slightly modified appearance of the toggle switches, which contained transistors in addition to the tubes for amplification. All previous Philcordas had slight differences in sound with a warm basic tone created by the use of cold cathode relay tubes. The range covers 4 octaves (49 keys) with 8'/4'/2' foot stops. The Vox I/Vox II/Vox III/Vox IV/Vox V registers, vibrato, and reverb are controlled via the reverb, vibrato, manual, solo comb., volume, and balance knobs. The volume is finely adjusted via an external pedal.

Like all Philicorda organs, the GM752 has a one-finger automatic chord system. This works by assigning chords to individual keys: pressing G sharp produces an E7 chord, pressing A produces an A minor chord. Each Philicorda has 17 pre-programmed chords (C - A7 - Dm - Eb - Em - F - D - G - E7 - Am - B - G7 - Cm - H9 - Gm - F7 - C7), but the key assignments have changed. The chord section is also the split point of the manual, in the lower section of which the organ produces a fixed sound in addition to the respective chords. (Source: Wikipedia)
