Good result Mike.
Often we discount that a transistor is the culprit and conversely we plump for the transistor without doing any checks. In your case having between 0.6 & 0.7v between B-E should have made the transistor conduct which it was with 0.1v above ground, so if all the feedback components, coils caps and switches were OK then replacing the transistor was the right decision, and proved to be the fault.
