    I cracked it – TR25 was bad after all, but is still fine on the bench, statically. I had it in the drawer, a BC172B.

    Good on the tester then but bad under pressure. I just shorted EC and found out the Beomaster switched off doing that.
    I hate that kind of fault! A transistor is dead but it wants to live when tested with low voltage…

    The BM1900 now switches off normally, and as suspected IC6 is good (it measured so).

    Thanks for looking.

    Wow!

    Gorgeous, well done once again 👍🏻

    That’s right. But the new forum allows about everything you might want to do anyway. The only – and very useful – interest of the app was to be able to take a photo directly for insertion in your posts.

    True. The Beolab 8000 and the pizza boxes are a joy to use and behold.

    I agree: don’t bother and just enjoy pressing the start button of a nice 1700 or 5000. Or of course a 4000…

    None can be remote controlled by B&O modern equipment. Try to find a nice mint Beogram 1700 of 5000. But you’ll need a phono preamp.

    J’ai donc pris le BM4400 et la BG4000. Merci Yann.

    Ça va prendre du temps à scanner pour les déposer ici !

    Salut Yann !

    Très intéressé.

    Je cherche pour la Beogram 4000, entre autres.

    Hello Steve,

    My favourite one remains the Beolab 5000 amplifier. No contest. Then, the mighty Beomaster 8000.

    In fact the small PCB in the Beogram sans  phono board has the same notches. Just remove it to see!

    Hi,

    I don’t remember but you can find them by looking where it is supposed to be seated inside the Beogram, right?

    I got mine from someone on the old forum who went by the username solderon29 – but that was 7 years ago so not sure if he’s active on the new site?

    Yeah, I also got it from him.

    Welcome to Beoworld!

    Nothing can be said from the pictures you display here. You really need a microscope, a good light source and some experience to do that. I use x20 magnification, more if I can’t decide. The worn surfaces are this tiny!

    Listen to a distinct lack of high treble. A dull MMC is a worn one.

    Yup, the idler is definitely the culprit for this noise. The usual flat spot plus hardened rubber. Nothing to be done here, just have it redone by a competent company. All three have to be done, by the way.

    Meanwhile, you can swap the noisier one with the one at right.

    Never mind the belt, but yeah, it’ll need to be replaced too. It’s a bit loose.
