After the BeoLounge some of the links were removed from the B&O site, but the product-archive, and some other pages too, are still there and work if you have the direct link.

The Stereomaster is now back in one piece and ready to go for action. I am not yet sure where I will put this (I might take this to work) but I will get it to be used somewhere. Looks great and sounds, too. Stereo decoder and original speaker - if someone has / gets one; I am interested!! Thanks for the tips and attached are some (more!) photos of the

I have never used an LC2. I still like the idea of remote controllable lamps; I have two LC1s, one of them is partly non-working (no remote control, only on/off by the touchpanel on the top) and I really enjoy using it. (It controls my bed-side lamp; there is nothing that stylish than going to sleep / waking up and switching lights on and off by touching

Thanks! I first tried carefully if the markings seem to be loose but they were firmly in place so I cleaned the whole panel from both sides. There are several bigger scracthes and even some rust in the lower panel so it can't be made mint but it will be fine. I didn't have any good sanding paper at hand so I just applied some bee-wax to the

I have now assembled the Stereomaster again and connected the internal speakers: it sounds like it worked! I am now running some tracks in thrue tape input and radio and I think it really works now. So the problem was simply a loose wire of the transistor. I also replaced the black caps (originally one cap of 64 uF 25v) and remade some of the ugliest

[quote user="tournedos"] Well, then you have one half-wave missing from the output since one of the transistors is out, and it will sound distorted... measure the transistor first before reconnecting it. If it is shorted, connecting it back may burn something else. [/quote] I actually already reconnected it; nothing exploded. The wire was

Some more founds: the red wire (as seen in the photo of the horrible-looking-solderings-and-newer-black-caps is loose) both from that board, but also loose from it's other end; the AD139 transistor on the rear panel! I will do some schematics study to figure out where it should be connected....

... the mains fuse and it's holder are horribly oxidized; that might have something to do with the lights pump. I will check around the power supply later on this weekend or next week.
-
There seems to be some power troubles as the lights pump a bit, too. Perhaps I should try to replace the output coupling caps and the power supply cap first? And to re-solder that horrible board. The coupling caps could be a logical place to start as the problem is clearly with only one of the two channel and might be because of it's coupling cap
-
I am now testing with the internal speakers now. There is a little segment of low volume that sounds good (not distorted) but once I raise the volume higher it starts to distort. Of course it's difficult to say as the volume is low and so are the deep notes. The headphone adapter (for the wired ones) has two about 120 ohms resistors (for using low
