They are 6 Ohms impedance so practically impossible to match today. Martin

The Beomaster 3000 has two Phono inputs. One has a built-in RIAA preamplifier (the other hasn't). I suggest you try the other input. Martin

Another thing is that not all link cables are equally good. Some cables will introduce a background buzzing from the speaker. Often, the amplifier (which works at full volume all the time) will also produce a buzz if no signal cable is attached. If in doubt, pull out the signal (link-)cables and insert an RCA plug that you can short. If the buzzing

Capacitors, yes. The Pentas are not as old as most other B&O's with capacitor problems but the majority of capacitors used in the Pentas are 85deg types and since they work in a warm environment, they don't last very long. The available capacitor kits contains 105deg capacitors with a slightly higher voltage rating in selected areas (power
