I have an early Beomaster 7000 (type 2341).

I do not use the amplifier circuit in it because I use Beolab Pentas as speakers.

The Pentas have been tested, and the 7000-amplifier separately, -the amplifier is the problem.

For a while ago it started to have a serious "hum" noise, coming and going. I think it was at the same time as the link system for the light control got really bad. I have 2pcs of  LC2 controlled by the Beomaster 7000. All IR remote control functions also lost a lot of the power.

This is similar to problems I have seen before here, but I can not find any information on it now.

Where can I get the full work shop manual for the Beomaster 7000? There is a 10 page version out there on the web, -but it should be more I think. 🙂

I am not an amateur on electronics, but the manual would help!

Best regards
