Anyone has the full list of faulty Texas Instruments ICs that affected the Voyager recall last year?
I remember having replaced a TL064 (U17 on the analog board) three years back which caused some erratic glide operation.

Hi ! i'm very interested in this list, my moog voyager old school 1,2 & 3 OSC died for the second time, and i don't want to pay for a new analog board that will die in less than 3 years.
thanks !

Thanks, do you happen to know which IC(s) is/are responsible for ADR time control of the VCA stage?
Is the VCA function actually performed by U20 (LM13700)?

No, unfortunately I don't. Try to ask someone at Moog, I hope you will find this out finally.
