Old keyboard, spares or repair. (Kelsall CW6)

Armon Super Piano portable keyboard, with lid and stand in a carry bag, 70s or 80s vintage. Full size keys, 6 octaves, sliders for vibrato and phasing etc. It requires repair as one of the divider chips has failed (TMS 3614 or equivalent). All chips are socketed so a repair would be easy if you can source the chip. Once fixed it would make a good practice keyboard but the sound is not good enough for performance.
