Hi Henryk,

apologies for reviving your old thread. Just wondering if your unit pcb 34 still have the same F1 and F2 125v fusses or were they changed out to 250v ones when the trafo were replaced with 230V version.

Hi Elvis,

To be perfectly honest, I’m not sure but reading service manual for Beosound 9000, they do recommend different fuses depending on type. Not sure though if type implies particular mains power rating or is it about power supply configuration. You will have to study UM a bit to get there.

Sorry I could not be of much more help here. It was quite some time ago…

Hello!

First, sorry for my english.

I red all your story with the Beosound 9000 problems..because i have a similar problem now with my Beosound 9000 MK1.

The ideea is that I.m trying to find the TR17 location..because i think this might be my problem ( When i power up my Beosound the red button is lighting, then i hear the relay click and the the red button is turning off..all this in 3-4 second, and then is cycling..again and again...and the equipment don't start )

And , with a friend of mine electronist, i am trynig to change the TR17 transisto..but i can't find it!

If you can tell me where to look..i would appreciate this very much.

Thank you!

Catalin.
