  • Re: Beomaster 3400 - sudden hum from the speakers

    Thanks Martin and Craig! I appreciate your input! I did try switching off all the electrical devices in the room but it did not seem to make a difference. I believe by now all the bulbs we have are LEDs, so I turned them all off, as well as the internet router; made sure the dishwasher, washing machine and such are all turned off. However, this did not seem to make the hum go away. I very much wish there was some easy fix to this, so perhaps I'll try once again tonight. If this doesn't help

  • Beomaster 3400 - sudden hum from the speakers

    Hi Everyone, so I started using my Beomaster 3400 but a hum problem has developed and perhaps anyone here would have some suggestions if there is anything that I can do with this... I started noticing a hum through the speakers. It is not there when I turn the receiver on, but at some later point I can hear it when there is no music or the music is quiet. I did some tests and a couple of times I turned the BM on, it was completely quiet and the hum kicked in suddenly about 30 seconds after power

  • Re: Beomaster 3400 slider potentiometers

    Dear Martin, thanks a lot! I just sent you an email through BeoWorld. I have to say I am very happy with the quadrophonic sound the Beomaster produces! It has a built-in SQ demodulator, and I listened to a couple of classical music LPs on it — I had the impression that walls and speakers dissapear and that I’m sitting in a philharmonic. Quite amazing!

  • Beomaster 3400 slider potentiometers

    Hi Everyone, I have one more question about the Beomaster 3400 — so it is now beautifully restored and works great. I hooked it up to a pair of P45’s for the front (which needed a lot of work as they must have been stored in a damp place) and P30’s for the rear and the result was magnificent. Howeever, it turned out during the repair that the horizontal potentiometer controlling the balnce between speakers 2 and 4 (rear) has a broken path. The people repairing it fixed with some

  • Re: Beomaster 1900-2/Beovox S40 - repairs

    Hi Jordan, I am not an expert but I can give you my 2 cents worth as I had to go through a similar routine recently as I am not handy with electronic and had to find the right people to service my equipment. I think I would take the equipment everywhere BUT B&O, I don't think they offer any kind of reasonable service for their older products (what qualifies here as vintage, at least). However, in any larger city you should be able to find local electronics technicians or workshops, possibly

  • Re: Beomaster 3400 phono preamp?

    Thank you, Martin, it is great to hear from the expert. The user manual I found online indeed states that there is a low impedance input with 3.2-2.6 mV/47kOhms, so that is what I assumed. However, I plugged in a turntable into Phono 2 and I get a typical no-preamp sound: tiny and squeaky. The turntable is not B&O, it is a vintage Pioneer with a modern, basic MM AudioTechnica AT95E cartridge, with an output of 3.5 mV, so something is indeed not working properly. I will take a look to see if any

  • Beomaster 3400 phono preamp?

    Hi Everyone, a quick question: does the beomaster 3400 have a built-in RIAA preamp for the turntable? My understanding was that there is a preamp at the stereo phono input, but not at the 4-channel phono input (since the assumption was that the Beogram 3400 will amplify the signal through the CD4 demodulator). However it does not seem to work on my BM3400 — should I be looking into repairing a built in one or am I mistaken and should be looking into setting it up with an external phono preamp

  • Re: Shipping disaster...

    OK, so here is the finished repair, the cabinet and the corner sanded and oiled. Some signs of damage is still a bit visible, but only after looking at it closely. Given the situation I couldn't really hope for more. Thanks for all the advice! I am now enjoying some good contemporary jazz played through the BM900K and trying out the different speakers - I have Type B and recently purchased Beovox 1600. I've seen the 1600 praised here on Beoworld before, but I must admit they do sound amazing

  • Re: Beomaster 3400 repairs - advice needed

    Hi Everyone, so I have a good scan of the service manual for Beomaster 3400. I am happy to donate it to Beoworld's library and to anyone who would want a copy. The only thing is that I don't know how to attach a PDF file here. Also do I need silver membership for this? Best, Piotr

  • Re: Shipping disaster...

    Mika, Søren and CB -- thanks for the excellent advice!!! It is extremely helpful! I will do as you suggest and refinish the veneer, there are some scratches on the top of the cabinet, and dry spots, that I would like to get rid of. I hope that when I'm done the damage will only be visible when looking at it up close. I bought this BM900K in excellent condition so it was frustrating to see it damaged by the shipping company. In any case, a pair of Beovox 1600 to go together with it arrived
