RE: [chromapolaris] Voice failed.... first things to check?

2017-01-25 by Paul D. DeRocco

I believe that the ICs are socketed in all Polarises. Unless they're not, a useful technique is to try swapping ICs between the bad voice and another voice, to see if the problem moves. The most likely are the 4051s in the sample-and-hold circuits, and the 4053s used for signal routing.
