Al: Again, thank you for your detailed post!
I'm going to trade in the 8 meter cables for the 5 meter to see if that improves things.
Also, I suspect an intermittently misbehaving preamplifier tube might be the culprit since the anomaly varies from time to time.
I just ordered a new set of tubes, just in case.
