I have'nt really had any issues other than a couple flakey bulbs on the VU's and PSU that I haven't bothered with.
the vu meters take a bit of time to "settle" into their correct calibration positions.
other than that functionally/sonically it's perfect.
I'm not sure but Peter told me a while back that he had a newer version Opto cell for my unit[Serial #002]
I should call him
