Levinson 33H buzzing on standby

Hi All,
I just noticed that my pair of Levinson 33H emits a buzzing sound from the tweeter when it is on Standby (blinking red).

When the amps are turned on, the buzzing sound goes away and is replaced with a slight hissing sound.

When I connect the speakers to my Levinson 433, there is no buzzing...so I'm guessing its not my power/equipment that is causing the problem.

I took the amps into my local service shop and they are telling me that its "normal" behaviour.

Does anyone (perhaps someone with 33Hs) confirm this is normal?

Thanks, Ray

Believe me, it is not normal for a ss amp on standby to "leak" out some current or something which causes a buzzing noise, especially on a mega buck statement amplifier. People move from tubes to SS for that dead quiet operation.

I would take it to another technician
