Hi all, some help please on Albarry amps

[cmgibbo]

Hi all hope you all are well?

I’ve just Recently brought Albarry AP4 + S508 preamp and power amplifier and I Really like it a lot, very
Nice sound,
The only one Problem is I can’t find any information about them or any specification,

And I do have a Small problem with the power amp I think?? When no music is playing I can here a Slight Hum from my speakers, I’ve Disconnected all the Inputs and it’s still there?

Any help would be much appreciate,
Many thanks Matt

Sadly Neil Burnett ( Mr Albarry Music ) passed away in 2016 and the family did no carry on the company

I also own a AP4 that had hiss priblems , Any competent repairer should be able to trace the fault and repair

I don’t think the problem is with the AP4, I can Turn it off and the hum is still there, with the s508 power amp on?

Many thanks Matt
