Description
Replacement for the obsolete TDA0470 and TDA0470D transistor array IC chips used for gating notes in the ARP Omni 1, Omni 2, Quadra, Solina String Ensemble, and others. If 8-10 keys in a row are out or problematic on one of these synthesizers it’s likely this gating IC chip. This is a drop in replacement and uses modern, less noisy transistors. Clamping diodes have been added (as per the TDA0470D) to reduce crosstalk. No need to gamble with potentially counterfeit IC chips anymore! Color of the module may vary.
