Customer Question

I have a Bang & Olufsen turntable (Beogram RX2) which has always worked fine. I moved recently and now find that there is no output going to the amp (I have confirmed that the problem is not with the amp). Mechanically, it is working normally, including the arm and stylus, so I think the problem must be with the output cable, unless there is an internal problem with the connection from the arm.

The cable is connected to the inside, so I cannot simply replace it. I have not found a way to open the turntable to see the cable's internal connection. Is there anything I can do about this before I send it out for repair?
Thanks,
Ted

Hi Ted,

  • The RX2 does not have a built-in pre-amp so will only work with your amp if the amp has a phono input.
  • If you lost your pre-amp or your amp phono input is not working, you can connect a pre-amp to the regular line input of your amp.

  • The pre-amp normalizes the signal by increasing bass, reducing treble, then increases the level of the magnetic needle cartridge signal and converts it to an audio signal that the amplifier can use.
  • The phono preamps start at $30.

  • The internal cable is not likely to be a problem.
  • More likely is the cartridge wires are loose or your connecting cable is faulty.

Relist: Incomplete answer.
Preamp is irrelevant here. He didn't answer my question: what, if anything, can I do that might possibly fix the problem so I can avoid having to send this out for repair.

Hi Ted,

  • You can manipulate the cartridge yourself --- see the link to the picture above.

  • Does your amp have phono inputs?
  • What equipment are you using to test the RX2 output?
