  • Beomaster 2400 muting always ON

    Dear Beoworld fellows, this is my first login and post after more than 10 years - the stuff has been working greatly up until recently when my Beomaster 2400 developed a fault. All touch commands work function without problems and all lamps are working except the treble one but the fault appeared independently...

  • Beomaster 2400-2 15volt transistor runs hot

    After a complete recap and cleaning (and a lightbulb kit from Martin) i find that TR27, the 15 Volt regulator runs very hot, at least i think its to hot, you can barely hold the heatsink. Is this normal or should i go looking for signs of trouble? And if so, where should i start? Thanks in advance, Marc

  • First attempt at Beomaster 2400 'refurbishing'

    Hello All, Starting my first real repair project on a Beomaster 2400 - no previous BeoFixing experience, but lots of electronic DIY. This model came from my Dad, which is why i said yes to try to fix it, besides always having wanted to having fixed a Beomaster by myself (counting on a little help from...

    Just as soon as i got the lid back on, new issue : Sometimes the sound mutes, when i turn the volume up. Only if i touch volume up shortly, like nudging a single step up in volume. Keeping the finger on volume up and it works just fine. Volume down doesn't have this issue, at least i have not been...

    After some deliberation, I turned the Beomaster on. It turned itself off immediately and gave a blue puff of smoke. Plus one of the 220VAC fuses blown. Finally i did, what Dillen has told me (and many others) to do from the start : Test/measure all components in the output stage. Nothing seemed to be...

    Finally got some spare time and got the 2400 out of the closet. Pulled the cooling fans off the output transistors and desoldered them all (IC200,201,300,301). Actually a lot easier than i would have thought, lesson learned. First one (IC200) came out in two parts, see the picture below and the Peak...

  • Re: First attempt at Beomaster 2400 'refurbishing'

    Got a little spare time, which immediately went into the Beomaster 2400 on the kitchen dining-room workbench (no room for guests this week). Looking at the 'volume up mute' issue, where volume would play briefly and then mute for the first 3-4 taps on 'vol up', I measured out 'any...

    I thinks this project is almost done. Did a FM tuner check yesterday, reception is surprisingly good, with only a short length of 0.75mm2 wire pushed into the antenna plug Only headphone hum left to fix. Tried two different jack-to-mini-jack converters and 3 different headphone types so an issue with...

  • BeoMaster 2400 service

    I recently bought a BeoMaster 2400 and it of course demanded some care and attention - I thought I'd share some photos I took along the way.
