The M70 phase link unit and the P45 woofers are optically very identical but that's where it ends. They have very different specs and will be far from interchangeable. In the M70, they don't really play much but merely fills in a kind of "void" (audible though!). In the P45, obviously, they are more than busy. Due to their identical

Hvis enhederne ikke er blevet udskiftet eller repareret men stadig er de originale, er de helt sikkert dårlige nu. Det er meget nemt at checke om de er i orden; Tag stoffet af. Se efter huller i kanterne på de store enheder, er der huller er de dårlige. Klem forsigtigt på skumkanterne og se efter revner. Er der revner, er de

First I saw it as a straight handle with ribs but now I see it as something angled with ribs, showed with the pointy part of the angle upwards. Martin

Sorry, but you have no idea how many times, I've seen this: Have you checked the speaker switches under the large lid ? Martin

Welcome from me too. The P45 woofers have rubber surrounds so will not need refoam'ing. The lose magnet issue applies, however. We've had that issue a couple of times. Do a search and read more. Get it fixed before moving them around any more or you will inevitably end up with more dead woofers. Capacitors are available as a kit as Søren

The extra darlingtons (the upper-most and lower-most in the stack) is for soft-clipping. They round off the sharp edges that would otherwise be produced when a transistor clips. This will protect your speakers (and ears), the tweeters in particular, since a square wave contains a huge amount of higher harmonics. Distortion from small amplifiers kills

You could check the potentiometers again but when you repaired the potentiometers, you probably had the whole tonecontrol board disconnected from the rest of the Beomaster. Depending on the exact version of the Beomaster, the tonecontrol board has either two or three connectors underneath and they are of different types. If yours are the type with connectors

Welcome to Beoworld and thanks for signing up as a silver member, your support is greatly appreciated ! B&O generally used 2N3055 transistors from RCA in the late 1960's but motorolas are also found in the later builds. Are you looking for both pairs or just one ? Factory new (NOS) or original used ? I take it, you are aware of the possibility

Nice work. " .. Also on power off the signal meter seems to go crazy and MPX light flickers eratically. Not sure why so will need to investigate this..." This is normal. As the voltages are bled down, the circuit will become unstable and produce erratic readouts. The signal meter pointer will swing up and down and the MPX light will flash

Det er helt OK, men CX100 har det samme problem som S55'erne så check lige om de er refoam'et. Jeg har faktisk også to par Beovox CX100, de er hvide, flotte og nyrenoverede, refoam'ede og med nyt hvidt stof. 1500.-/par Martin
