Jon,

You mention that you have found some points of sensitive where the hum may 
be entering the IF circuits.

Please take some time and give us some details of what you found and where. 
It could help someone else someday. These discoveries should not be left un 
published. You work hard for this knowledge. Please share it.

Thanks 
Roger Ruszkowski
