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

Thanks to all for the responses.

The tech was able to repro the buzzing sound just by hooking up a power cord and a speaker at his facility...so I don't think it has anything to do with my connection or equipment.

The tech called Levinson/Harmon and talked to one of two only remaining technicals from pre-Harmon days and was told that the sound is normal and not indicative of anything wrong or about to go wrong.

So now, they don't think there is a problem. Sigh...

Is it worth asking him to replace the capacitors?
