  • Re: BeoGram 8002 Microprosessor

    I'm doing some research on my own broken BG8002 so I found a thing or two about it. Do not throw away the microprocessor chip yet! There is no replacement anymore. First make VERY sure the chip is broken. It could still be something else, e.g.: - electrolytic capacitor anywhere else in the machine. Replace them all. - broken solders, especially on the connectors and inside the microprocessor can. Resolder these and inspect thoroughly! - broken trace, especially around connectors and inside the

  • Re: MX7000: DTV ontvanger bedienen met beolink 1000?

    Jammer daar was ik al bang voor! Haha deze MX was al een koopje. Bedankt voor de tip, ik zal marktplaats weer eens in de gaten gaan houden.

  • MX7000: DTV ontvanger bedienen met beolink 1000?

    Hallo allemaal, Zoals de titel zegt, ik heb een MX7000, ik denk uit ongeveer 1992 (type 3380). Ik heb er een Topfield KPN digitenne kastje bij. Ik heb hem aangesloten via V.TAPE 2. Wanneer je het KPN kastje aanzet gaat de MX aan. Leuk! Maar het zou het mooist zijn om hem met de beolink te kunnen bedienen, aan met de TV knop, zenders kiezen... Ik heb al gelezen dat je daar een STB controller print voor moet inbouwen. Kan dit bij mijn MX of alleen bij de nieuwere Beo4 types? En waar vind je zo'n

  • Re: Beolab 4 humming problem

    This is probably noise from the PSU and processor inside the samsung. In a headphone you won't hear this but the sensitive input of active loudspeakers like BL4 can pick it up from a TV headphone output and amplify it. You need an attenuator in between the TV and the BL's. You can a) build it yourself: Hissbuster b) use a headphone volume control, eg this one . Insert between the TV and the BL and set it at 1/4 or half volume (or adjust to taste). The volume control on your TV will also become

  • Re: My Beogram 4002's transformer is bit noisy

    An old trick: halve two squash balls and use them as dampers under the beograms feet. Should dampen the buzzing enough. Most of the noise will be amplified noise from the table the beogram stands on. The platter etc are buzz isolated by springs so will not pick up the humming and send it to the amp and loudspeakers anyway. I agree changing the transformer is doubtful as it will be the same transformer you already have...

  • Re: My Beogram 4002's transformer is bit noisy

    Where are you located and what is the mains voltage there? Here in the Netherlands AC power used to be 220V, is now around 230V. Setting humming transformers to 240V sometimes cures these kind of problems, because 230 is sometimes to much for a 220V trafo. Maybe the same applies in your area. The voltage selector is probably on the back of your turntable. First make sure of the mains voltage, if the setting on your beogram is incorrect unplug turntable and change the selector switch to the right

  • Re: Beovox MS150 behuizing vervangen en daarna..

    Leuk project! De baspijp is 17cm exact, en inderdaad 10 cm diameter, misschien net een millimeter minder, door de ronding aan het uiteinde kan ik hem niet exact meten met mijn meetlintje. Het is een kaarsrechte pijp. Ik ga ze niet openschroeven, genoeg werk aan gehad bij het recappen, :) maar het MDF van de kasten zal een centimeter dik zijn, met een uitsparing aan de voorkantwaar het front in valt. Het vulmateriaal is gewoon schuim, op de site van sonavor wat foto's, moet je wel mee uit de voeten

  • Re: Crossovers

    Interesting experiment. But did you already install fresh capacitors in the old crossovers, did you recap the penta amps and redo adjustments? Because that should make them sound exactly as new. A random monacor 3 way crossover will never give the sound B&O intended. And I like to think with the time and recources B&O invest in measuring and perfecting their loudspeakers they gave a fair amount of thought to the crossover design. If a simple crossover were just as good they would have installed

  • Re: Correct input voltage for IR code converter

    Mine is 9VDC 500mA. However my converter only works intermittently and I haven't looked for the cause yet, this voltage might be too low. The adaptor that came with mine is not official.The converter calls for 8-14V, maybe better be on the high side of that. What is important is the connector pinout: the sleeve of the adapter carries + voltage and the tip the - voltage, contrary to what one would expect from most adaptors! PS: thought I already sent this but something went wrong, now I see 2

  • Re: Correct voltage for B&O infra-red code converter box

    The text on the converter says 8-14V DC. Mine has an adapter that used to be from a phone, 9VDC 500mA with the + on its sleeve and the - on the pin, so inverted from what you'd expect from most adapters!
