The harman/kardon 330B is a classic mid-1970s (1974–1976) stereo receiver, celebrated for its warm analog sound and minimalist styling, with the black/green dial and the translucent red power button that illuminates when on. It's a solid-state unit, typically producing 20-25 watts per channel into 8Ω and features "Twin Power" design, with separate power supplies for each channel. In addition to some cosmetic detailing--in-house--our tech performed the following:

  • Fixed shorted outputs
  • Replaced defective capacitors
  • Replaced lamps with LED
  • Replaced power resistors
  • Replaced broken fuse holders (L/R Channels)
  • Replaced all electrolytic capacitors
  • Replaced fuse holders

Everything was tested and found to be fully functional and sounding nice and warm. It's ready to take on another half century of work looking and sounding fantastic.

  • Power Output: Rated at 20-25 Watts Per Channel (WPC) into 8Ω
  • Inputs: Phono (MM), AUX, and Tape
  • Outputs: A/B speaker switching, supporting 8–16 ohm speakers
  • Tuning: Analog AM/FM with signal strength and tuning meters

Cosmetic Condition: Light cosmetic wear to face & top (see photos). Back panel has a rusty area at upper right (see photos).

Electronic Condition: Excellent
