Beomaster 2400 Humming in the boxes, specially on radio

Reply Contact

I´ve a Beomaster 2400, really great looking in oak in whith a good sound. But there is a humming in the boxes, specially when radio is on. I opened it from the bottom, "TR-27" looks a little bit unusual. What can I do?

Welcome to Beoworld ! Yes - thumbs up

Check that the mains voltage setting switch is set according to your local mains voltage.

Still no luck - replace capacitors. A kit is available.

The humming continues in 220V or 240V setting. What ist "Tr-27"? Maybe I first change this?

TR27 is not the reason for the humming.

Aging capacitors and the board mounted rectifier are the greatest candidates.
