[sdiy] Prophet 10 op-amp swaps?

[Oakley Sound]

I did my Prophet 10 swap out with OPA134. I typically check for things 
like oscillations, noise and offset problems. No such things existed 
with the OPA134 - although I could have been lucky with a marginal layout.

You could try an extra 33pF capacitor across pins 2 and 6 of each EQ op-amp.
