[volt-nuts] 7081 AC buffer *again*

House standard should be pretty close as it's a Trimble Thunderbolt GPS.  However, I don't *think* that is the culprit as thjis is just "close to" 10MHz, rather than "spot on".

So yes, oscillation is likely.

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

100 mV P-P is fairly substantial.  Otherwise, is it oscillating?

Good luck.
