  • Re: Beogram 7000 tone arm assembly not moving

    I agree. It's on the wrong side of the white bar. You need to release the right end of the rearmost steelrod from the base and correct it. Martin

  • Re: Beovox C-75 recap

    Welcome to Beoworld ! The C75 is a nice speaker and it's getting rare. The crossover circuit is quite simple. The capacitors are not very critical in this circuit and any decent quality bipolar electrolytics will be fine. Any well-assorted electronic components store will have them. I can also supply the capacitors but there's not a dedicated

  • Re: Beogram 1700 speed issues

    Eric, Welcome to Beoworld ! I'm almost sure that the "alternative" speed is exactly the double of the normal, that is 66rpm instead of 33. This is almost always caused by a slipping belt. The motor will spin up too easily, it will reach a too high speed and the electronics will happily lock it there. There can be other reasons but a worn

  • Re: Bang & Olufsen mini 510 (rare?) on Lauritz.com, Roskilde DK

    Mini 510 RG An FM/AM radio with built-in record changer. - Rare ? It's not the most often seen model, that's for sure. - Desired ? Not really a lot. - Why ? It's a radiogram. It's really a shame but the radiograms are generally, with very few exceptions, not considered attractive and sought after. It may be because they take up so much

  • Re: Mini 513 Valve Radio.

    Great to see it again ! Actually, after Richard bought it and it spent a little time on my bench in Copenhagen, this Mini was brought back to Struer. It had a brief visit back home, right at the parking lot in front of the factory, before going to the UK. It's in fabulous condition and it looks so wonderful with the lit magic eye. Martin

  • Re: Bad FM reception, Beomaster 3000-2

    There can be several reasons but first things are : Beomaster 800 : Check the power supply voltage setting and replace caps. Beomaster 3000-2 : Check (or replace) the black square rectifier in the corner of the tuner board and the filter cap right next to it. Martin

You will experience that the relay works for now but it will soon fail again with the contact surfaces now open to airs moisture etc. If you look at the contacts in a microscope

  • Re: Beomaster 5000 questions

    Welcome to Beoworld ! The Beomaster 5000 uses a digitally controlled potentiometer in the form of an integrated circuit. Nothing to clean here and, luckily, it's not where the problem is. You need to replace the muting relay (on the preamp board, near the connector bay). The problem is well known and will only affect speaker set 1 which is the set

  • Re: BM4000 Down!

    Nice second-life use for that switch and a nice project ! I think, I would have chosen shielded leads and connected directly to the switch rather than the DB25's. Well, maybe you can add alu foil to the inside of the box to shield from noise etc. but the telecom leads may still worsen the signal separation (capacitance between close parallel leads
