Frank,
Your original Q4101 should have been a D2012, and from a quick glance at the
two spec sheets NTE2311 should have worked, so I would guess that's not your
problem, just a symptom. Check your regulator U4101, which should be a
STK730-010 and will cross with a NTE7125. Also check CR4122 and your 333k
resistor at R4110, which may be taking a quite a stress if it is your
regulator.
Hope this helps...
