I have my Beosystem 5500 connected with Beovox Penta´s.
I can hear a humming or distortion sound from the speakers. Is there a part I can change to fix this?
"You think we can slap some oak on this thing?"
Has it always done this or is it a newly developed problem?
Can you connect the Pentas to another source? If the humming stops, it's a part of the BS5500. Is it an Earth hum? Can you try new cables? Are the cables connected 'in-phase' properly to the speakers?
Dave.
IO have had the pentad connected to a icpower-amplifier. Then there is no hum. So it is definitely the BM5500 that has the hum.
When i turn the volume up from 00 to 30, it gets higher an higher, at 32 it drops down, and from 32-50 it gets higher, and at 52 it drops down really low.
I would say that it sounds like an earth hum, yes..
The sound is also ppresent if i connect my BL4000 with rica-cable through the line-out on the BM5500.
Replace electrolytic capacitors in the power supply.There are about a handful smaller caps near the voltage regulators, 10uF and 22uF, they areknown to give this kind of trouble.

Do I just change them by desolering and resoldering new ones? Or do I need to do any adjustment to voltage or something?
No adjustments needed if you just replace the capacitors.Get the polarities right.
Would you happen to have a kit ready for sale, Martin?
I´d rather pay the extra to know that I am getting the right types, than to open it op to check them first :P
Thanks but there's not a dedicated kit for this.It's merely a couple of small caps, available everywhere.
