It is mostly a layout and wiring issue causing *positive* feedback.
Make sure no output signal is being coupled back to the input by stray capacitance.
Is the output transformer metal grounded?
All wiring shielded?

This is an issue that has been ackowledged by the company as an issue in the early production units.
This is one of those units, it HAS a design problem.
** All stale news.
Why bother posting here if not to get tech advice?
You are one rude, stupid prick.
