Medogsfat: MS150's are often touted as being the best passive speakers ever built by B&O and are the recommended ones for the Beomaster 8000. Most will now require refoaming of the Bass & Midrange drivers though if not already done. They tend to be quite expensive even in poor condition. If you find some (as with all this speaker range)

Tried the above, with exactly the same results. I'm going to assume, tentatively, that I have some kind of fault in both speakers. They do get as far as going into standby when powered-on, then out of standby when fed with a signal, so at least part of the logic in both speakers is working. But the lack of both sound and data display suggests it's

Got my pair of BL 5000s, from a guy who had bought them used but never tested them or seen them working - he didn't have any other B&O gear to test them with. Here's the situation: I hook them up to power, and to my BM 3500 via Powerlink. This is exactly the same hookup that works perfectly with my Penta 2s. When power is applied, the red

camshaft: Hi Mike, Are you talking about those beolab 5000's that were on ebay and didn't sell for his starting price of $600? I was tempted by those also, but I've got too much on my plate to worry about right now. Those are the ones I bought; the guy was not too far away so we met half-way and did the deal. $500. Actually, they're

Dillen: I agree with Chris. Many owners are in for a huge surprise when replacing the old capacitors. Electrolytic capacitors only have a limited life span, maybe 20 years and, let's face it, both the years and the caps have gone by now. New caps will restore the original sound and we can take it even further with the Penta's; A Beolab Penta

Well I signed-up for silver membership, and the manuals proved helpful... removed the amp and base, wiggled the connectors on the tweeter/woofer board, and normal service was restored. So we have a fairly nice working set of sub-$500 Pentas Frustratingly the speaker went back to midrange-only when restored to a vertical position, a judicious slap to

camshaft: If you pay for the silver or gold membership you'll have access to the penta service manuals which show the full disassembly and schematics. As for your actual issue: The pentas use two separate circuit boards for the crossovers. One board handles the midranges and the other handles the tweeter and woofers. If you're certain that only

Well my Pentas are now looking nice and clean - Lysol kitchen cleaner spray, followed by Duraglit metal polish/cleaner was the answer to the cosmetic issues, thanks everyone! But one of them doesn't sound so good... turns out the reason for this is, only the midrange speakers are producing any sound. I'm not remotely familiar with Pentas, or

Just got a pair of slightly old and tired Pentas. Quite apart from any electrical work that may turn out to be needed, I'm wondering about the cosmetics: 1. What's the best way to clean/polish/restore the somewhat dirty and tarnished metalwork? 2. Any advice on cleaning/restoring the speaker covers? Are replacements readily available? 3. Inevitably
