Is it possible that it is, somehow, 'picking up interference' from your 'house
standard'? How close to 10.000 000

I agree with JL - it's either picking up an available frequency, or making its
own. Oscillation can happen with transistors, especially any common
I've returned to the 7081 that was giving me troubles in the AC buffer circuit.
Probing the output test point (TP 705) I'm seeing about 100mV pp (approx) at
about 10MHz. This would likely explain the strange results I was getting last
year. However I'm puzzled as to where it can be coming
