  • Re: Beomaster 2400, 3000, 4000.

    I started with beogram 2400, recapped, Power on and all indications are working, but sound is muted. Is it possible to "bypass" the mute switch? I am resorting to my signal gen and scope to check further . I've spent too much time trying to get this working?

  • Beogram 2400 refurbishment

    I've recapped the 2400, the unit powers up and all indicators work as well as selections of phono, tape, FM1 to FM5 , the volume indication up/down works. Checked power OK but no sound. Is it possible to "bypass" the mute electronic function and could it be done and what is the risk?

    Being very new to B&O products, I have been completely bitten by the sheer "magic" of the technical engineering of all the vintage products. I have aquired 4 turntables,5 amplifiers, 1 tape deck, Beocentre, of which some are in working and beautiful restored condition. Then I have multple Beomaster amplifiers, 1001,2400,3000, and 4000. Coming from a electronics background I have repaired and restored only a few B&O amplifiers. I,m still getting aquainted with fault finding and repairs

    Morning Martin, Thank you for the reply, I do have 7 faulty Amps (All vintage B&O 4000, 4400, 1700, 1600, 1001's on my workdesk and three turntables and just started. I have also aquired an oscilloscope, I,m in South Africa, and these amps are ending on my work table. I have made up my mind that if I found 1 faulty electrolytic i replace all. On the 4400 it's quit extensive job. You were right all the drivers are either leaking or faulty when tested. I have bought new replacement spares

  • Beomaster 4400

    Hi Guys, As I'm new to this forum but have a few B&O products eg, turntables 2402's 2403, etc, and B&O beomaster 3000/4000, 1600, beolab 1700. and then 4400. The 3000(4000) no stereo, and balancing L & R not working only L yet output on both channels. This is what I do not understand. The 4400 switches on briefly but then OL on for few mS thats it. I haven't really started allthough checked the drivers that seem OK. Can I disable the OL switch and what happens?
