  • Re: Beomaster 3000-2 help needed re-wiring

    Thanks. Watching one, I realised it's missing the whole flexible circuit to connect to the presets... Could probably work it out and replace with wires. Also looks like the 300-2 2402 in the video has a different board. Mine has tabs for the pot connections.

  • Beomaster 3000-2 help needed re-wiring

    Hi All, I have a Beomaster 3000-2 that I am repairing. At some stage the radio section was removed (by me in the distant past) and I need help working out the wiring - specifically where the manual tuner pot is connected to on the switch panel board. I have the schematics but they do not show the switch panel connections. Any good photos or diagrams really appreciated. Thanks for any help! Theo

    Success! With new caps and rectifier, (generic 200V one) its working perfectly. Sounds much better too, the crackle and pop on turning on has gone. Very happy. Looking forward to another 43 years of groovin' (the amp, not me!). Thanks for your help Martin, Theo

    Hi, can you tell if the capacitors are wired correctly? Negatives are all to the right in the pic. Thanks.

    ok, no, unfortunately don't have that function.

    left to right looking from the back, they were: 10K, 35K, 35K and 35K. Again not very stable to read, but tge leftmost was definitely lower than the others. Thanks, hope this is getting somewhere! Theo

    Hmm. the reading is not stable and climbs steadily from about 20K, settling at 50K. Same for both sides. (no power connected of course, perhaps my meter battery is a bit low.)

    Between red/white and red leads, its zero, because they both connect to the same contact of the centre power output cap. If I disconnect those pins (they unclip from the board) the reading is 128K. The reading across all four red resistors is 1ohm.

    'low' is zero and 'high' no reading, on my meter. I guess this means it could be the output stage. But is it worth replacing the rectifier? Thanks

  • Re: Beomaster 2402 - blows fuses

    OK.. I do know how to test a diode, and my meter readings accross the rectifier do not look right: from 'red' input to output is low (resistance) from 'white' input to output is high (should be low) from earth 'out' to red and white input is high resistance (should be low) Hope this makes sense, but it looks like all but one (red to + out) diode is blown. Is its worth replacing this, or is this just indicative of a more complex fault? You are right, that if its more complex
