Classic STAX electret system: SR-30 Professional earspeakers (Pro version introduced 1989) with the matching SRD-4 adaptor (model introduced 1975), made in Japan. The SRD-4 connects to the speaker outputs of any power amplifier (input cable with bare ends), and passes your speakers through via its rear terminals. The front switch selects Loudspeaker or Earspeaker.
- Both channels working perfectly, tested.
- Earpads show age (cracked faux leather). Replacement pads are available, and the drivers are unaffected.
- Original headphone cable.
- No original box.
Electret: no bias supply needed, just a power amplifier.
