Hello,
I´m currently resurrecting my vintage B&Os, brought back to life two Beomaster 1900 and a Beocenter 7002. But now a Beomaster 3400 is challenging me. If i turn it on a humming sound is coming out of all 4 speakers, volume, tone and balance controls are working. But there are no lights turning up and no real sounds coming out of the speakers. I didn´t find the service manual for this model, has somebody got it or a source for it?
Thank you to our Sponsors

I lately discovered your message
Concerning the Service Manual I may send it if you are still interested.
Cheers

You should start by checking the power supply voltages and the electrolytic capacitors.
Yes, I‘m still interrested in the manual. I‘ve allready changed a lot of the capacitors, because some of them were obviously gone.
