It has been seen before so not a bad idea at all ! Martin

Yes, it answered my question in that it was NOT S120.2 but MC120.2 Some of the best sounding speakers for their size, in my opinion. From the front everything looks original and fine, though the woofers obviously weren't refoam'ed yet. Martin

- or mail them to one of us if everything else fails. Are you sure they are Beovox S120.2 ? I saw S120 and MC120.2 but never S120.2 Martin

Hej Jan, PM til dig, check din inbox ! Martin

How does it sound, then ? Without doubt, the quality of the sound reproduction depends greatly on the choice of programme material. I have recorded a good minute of the sound produced by the Beolit 39 so you can hear what I hear. For this recording I'm using a Tandberg TM6 microphone which is the best I have at hand at present and by far adequate

There are many different versions of 4002's. This particular one looks like a type 5511, 5521 (or maybe 5525) and there seems to be some confusion in the service manual. D17 is shown as a zener but listed as a 1N4148 (which is a standard diode). Judging from the colors of the diodes on your board, D17 definitely looks different than most other diodes
-
If you have another amplifier (or a neighbours/friends etc.) you can test the speakers using that. Maybe that will confirm if the problem is with the speakers or something else. You can take a photo showing the front of the speakers with the cloths removed. This will show us the front side of all the drivers and often be enough to tell if something
-
Jeff, I agree, they shouldn't sound like you describe. They are usually quite well balanced soundwise. Any chance you can post photos of the drivers and maybe the crossovers ? Martin

I never owned an original wallmount of this type myself but I believe it is more or less a flat metal plate, bolted to the wall. The Beomaster grips the plate using the little grooves on the sides of it's square plastic feet. It's hung on the plate like a painting on a nail in the wall. Martin

Yes, put an oscilloscope to the signal path and note where the signal is lost. It will also tell you if it is indeed a capacitor problem or something else. Any good electronic parts store will have suitable capacitors. Martin
