IG00150: Spare from another board

If one of your IG00150 has gone bad there is an alternative to get a "spare" from a lesser used module in your CS-80: The chorus/tremolo board (OE1) has two of them.

OE1 Board

I don't know about you, but whenever I switch the chorus or tremolo tab on it has a bad impact on the sound, makes it somewhat dull and boring, even when I just switch the tab on without activating one of the two effects, so I actually never really used it.

During calibration of the CS-80 the IG00150 of the ring modulator failed all of a sudden. After it was clear the IG has gone bad, it was a quick decision to steal one from the OE1 board.

I even went a step further and removed the second one from the OE1 board as well and stored it in a drawer as a spare. If I don't use it, it's better to keep rare custom chips outside.
