Vtg Bang & Olufsen Beomaster 4000 Receiver Parts or Repair Partially Tested READ. In very good physical condition. The only flaws are a couple of water spots on the top wood grain(see last 2 pictures). No other flaws or damage. Functionally, has been partially tested w/ headphones and FM only. FM came in clear over phones, presets worked, and balance, bass, treble, etc seemed to function properly. The green stereo light illuminates, but the red power light does not. Did NOT test w/ external speakers or components. Reach out w/ questions.
