hello, my tuner has a hum with variable volume based on the setting of the output potentiometer. I isolated the transformer with rubber washers with some effect. Is this a transformer line problem picking up another appliance or something else internally.thanks

I wouldn't think it is your Tu-717.
Clean it out first.

Mine takes alot of abuse.

Buy a power strip, and try again.

Regards,

Joe
