Just realised I still have this. So...for sale: 1x LC1. Some scratches and dings, still looks good as long as you don't get to close. Had a general overhaul some months ago (all caps are new) and is working just fine. 220-240V model. Just the LC1 - no cables, no wall mount, no instructions, nothing. Asking price is 130€. Shipping to Europe

So after fixing the power supply and the left amp I'm finally testing the Beolab. One thing I noticed - both the AUX and Tuner connections were not working. I just assumed there was a fault in the preamp, but then I remembered that upon receiving the Beolab I had actually used the AUX-input for testing - though by using a RCA-Cable rather than a

You know how sometimes you spend an eternity looking for a problem, and then suddenly you stop and think: "Wait, have I checked...? I mean it's obvious, I'm sure I have...right?". Well, then you know how I feel right now. I was measuring the supply voltage to the amps. You know, the voltage behind the power supply section. The voltmeter

When the base is grounded, it oscillates between 1,7V and no connectivity. Excuse my ignorance, I was born long after the days of germanium semiconductors. There are 25V after the diode, I haven't measured further down the line yet. Just bypassed the preamp, and yes, it works fine. Just a bit too quiet, if you know what I mean. Strange. I checked

Thanks for your input! Replaced the diodes with 1N4001s - still nothing. Checked the capacitors - capacitance and ESR both measure out fine. Checked the transistors out of circuit - they also measure 1,7V e->c...they shouldn't do that, should they?

Does anyone have a good quality scan of the preamp-schematics? I can't really read most of the things on beaker's scan. What I've found so far: AC126...wasn't it those that grow crystals or something?...both test ok, but the breakdown voltages measure about 0,15V on both transistors, whereas on the other two (2Nsomethings) it's the

Thanks to Martin, there finally is some progress: For future reference: The bearing on the ST/L and the Beogram 1000 tonearm is identical, the arm itselft is not (the ST/L arm is longer due to the different counterweight). So...bearing replaced, adjusted - speed is perfect, tracking weight is perfect, arm perfectly adjusted...put a LP on there, take

Somebody please buy this! I'm moving out in two weeks and I'm not taking this with me. But you know what? If nobody does, I'm going to put it in a nice, solid box and store it away in a dry place for the next 10 years. And then I'm going to offer it for 500€. Minimum. (If the € survives for another 10 years.)

No, I don't. I just thought it'd be better to translate it right away - before someone uses Google translate and ends up thinking "what the hell did B&O just say about my mother?!". Anyway, the system is still for sale. I still haven't been able to take decent photos or even put up an auction. Also, I'm not home most of
