  • Re: Transformer Spec for BG 4000

    To me the 220 V through the secondary of a transformer is the same signal as the one from the wall outlet (220V - 50hz) apart from the fuse protection that would be missing and need to be added. I will contact Toroid corp , but I am afraid that the transportation cost could probably lead me to find an european manufacturer

    I will probably go for a 220 V only transformer. I would prefer to have a toroidal model in order to have a better audio signal without any Hum, but it will be probably diifcult to find a small one that will fit in the space, with the 3 outputs Why is it better to get the strobe signal from a secondary 1/1 instaed of the primary ?

    For a new transformer - how many Ampere is necessary for the 24VAC output ? - How many Ampere is necessary for the 6 VAC output ? As the main power is 220V , can I connect the strobe directly on the line voltage with a fuse in between ? (what should be the amper value of the fuse ?)

    Yes but it should be the same transformer for every voltages I was meaning that I the 5 inputs of my transformer are not connected the same way as yours. Your schematic has more sense to me in the way that you keep one 2 inputs Red/White (upper) separate coil and a 3 inputs coil (Lower) Yellow/Green / Black. My schematic is using a B&O schematic on which I simply apply the cabling color effectivly present on my BG4000.

    But the wiring diagram that I deduce from my system is different than the Sonavor One :"https://forum.beoworld.org/forums/p/13217/118750.aspx"

    I Remove the transformer to take measurements. here are my results: The inputs seems Ok to me, there is only the Red Output (675 Ohms) which seems to be wrong.

  • Transformer Spec for BG 4000

    Hi Guys I am currently trying to repair a BG 4000 (thanks to Sonavor and Beolover who gave me the faith !) My (first) problem is related to the transformer that seems to be faulty. One of the two 250 mA Fuse blows directly when powering On. My country voltage is 220 V - 50Hz I plan to buy a new toroid transformer . Could you tell me what would be the spec of such a transformer ? What is the solution for powering the strobe light ? Thanks for your help

    Do you plan to authorize any DLNA renderer to be used with your app ? (today you can only add DLNA server as music source)

    Thanks Theomaster for your nice global view of the B&O cabinets I did not thought about black or white painted feet/stand (but why not) !! I was much more thinking about chrome plated feet in addition to Alu feet.

  • Question about B&O Cabinet

    The vintage B&O cabinet (MC 30 or SC20, SC 70 SC 77) were available in différent wood finition (rosewood, teac and oak as far as I know) but do you know if the metal feet (stand) of theses cabinet were also available in different finition or or was it only the silver Aluminium finition ? thanks for sharing your knowledge
