ABR pladerne (Auxillary Bass Radiator) kan ses som en dynamisk forlængelse af kabinetternes rumindhold. Ved at ABR pladerne "spiller passivt med" ændres rumindholdet af de slanke kabinetter, så man faktisk snyder lidt med størrelsen og får en bedre bas-gengivelse end det ellers ville være muligt i de forholdsvis

The newer U664B comes in several different versions but none of the ones I have tried worked. I remember one of them just flickered the digits wildly and I switched it off rapidly. I have a few original IC's still in stock but if you can get an original IC for less than EUR 10 in Germany, I suggest you grab it and run. That's about half the

Velkommen til Beoworld ! Det afhænger af typen. De har hver deres standard-fejl. Det meste kan dog klares. Kondensatorer i delefiltrene bør under alle omstændigheder udskiftes. Der findes kondensator-kit til de fleste modeller. Nogle har problemer med skum-kanterne på bas-enhederne og eventuelt på ABR pladerne. Dette kan

Sveifors, I am using it with 4 pcs of JAMO POWER 555 speakers which it drives with ease. I like the sound of these speakers and actually prefer them to B&O's passives. Should I choose a pair from B&O, it would have to be MS150 or MS150.2. The MC120.2 are also superb speakers and not quite as large. The Beovox M150 is a bit too tight sounding

As I understand it, neither SPK1 nor SPK2 or headphones produce any sound in the left channel, which rules out the relay. The relay fault only affects SPK1. It's very common to see lots of cracked solder joints in the connector bay. It's also possible to flip the signal cable to the power amplifier left/right to help diagnose but if you are

You will indeed use the tape socket. The record signals will be taken to the PC since the PC will act as the recorder. If you also feed the playback signal the other way, you will be able to play from your PC through the Beomaster by selecting Tape. Martin
