Allo Volt+ D issue

[johnk-]

Hi,

I have been very happy with my Volt+ D, but recently I think it is developing a fault.

One channel has developed a low frequency buzz and I can hear a speaking through it like it is picking up a radio station (AM interference I guess?). I tried the AM avoidance switches, but there is no improvement.

The other channel is as quiet as ever. If I was to guess I would say the buzz is a 50Hz mains hum.

I have been running using an Alitove 24V PSU as recommended in other forums.

I am happy to do some debugging if you can point me on what to try, but I only have a multimeter to test things.

(My Volt+ is still running perfectly 🙂)

 Thanks,

John

Well this is embarrassing. The problem is with my source, not the amp. The Volt+ D is working perfectly.

Thanks again,

John
