Hi Peter,

Thanks for your quick reply!

It's the US model. (120V). As the wires on the mains transformer are all well cut I am not sure if I have the correct output voltages when I resolder them and connect it to the mains (120V or 240V). It seems that its one transformer block, but for 120V both sides are parallel. I would like to put them in series to be able to cope with 230V (Which normally would result in 2 "blocks" of 115V). Still the question what the output voltages shall be. (input and output wires are well cut, it's a transformer without wires).

For the sound input... that will be the next thing to look into. I do have some ancient but small NTSC-PAL-NTSC conversion box, which might be built in. Could be other options though?

But any way, I would just like get this thing to work on 230V and be able to send the sound to my speakers. Dolby Surround is a second thing.

I don't have any docs on the AV7000 but maybe the transformer is the same as in the Beomaster 7000, have you checked ?

To me it's not the same.

Now I 'm trying to puzzle through the scheme myself and figure the voltages. (it seems something like 12 / 24 / 15 / 30 or so... )

Now only the issue with the NTSC connections.

I would also like a schema on AV7000, anyone who knows where to get it? It is not on Beoworld..

For changing 110V versions to 220-240V there is a good picture on the European model with the correct connections to the transformer here:

Got one myself and did the
