Forté 1A - buzz problem!!!

[lukesound]

Hello,

I have a buzz on a left channel on my Forté 1A 🙁

I have tried to detach it from the preamplifier, but the buzz remains.
The buzz is perfectly audible from my listens point.

The two channels work to the same temperature ( touching with the hand ) and I do not feel losses of balance.



Someone of you knows the reason?


Thanks

Luca

Most of the time it is a ground loop issue. Create a pair of
RCA shorting plugs and use them on the inputs. If the noise
persists, then it's the channel. If it goes away, it's a ground
loop.

Hello Mr. Pass,

I have made a test with these net filters:

Now all good!

Probably it is only a problem of the net electrical worker of my house.


Thanks of all!


Luca 🙂
