RA-Twin II Gold Series RX Bundle, $69.00 →Gorgeous Vintage Harman Kardon 30 WPC Stereo Receiver in custom Cherry Cabinet
This beautifully preserved Harman Kardon 630 Twin Powered receiver is a rare vintage classic, now elevated by our comprehensive Level Two service and a stunning, handcrafted Ottawa Valley Cherry wrap-around cabinet. In very good condition both sonically and visually, this legendary stereo receiver is renowned for its robust dual-mono construction, producing rich, dynamic sound and unmatched reliability—a true showpiece for collectors and discerning listeners alike.
The HK 630 features Harman Kardon’s celebrated Twin Powered design, providing independent power supplies for each channel. This unique architecture ensures superb channel separation, exceptional detail, and the ability to drive demanding speakers with composure and authority. The receiver’s warm, “tube-like” signature makes it a favorite with vintage audio fans, while the smooth linear tuning dial, gold-anodized aluminum knobs, and minimalist display bring timeless style to any setting.
Essential features include inputs for phono, auxiliary, and tape, as well as pre-out/main-in jumpers for flexible system integration. Thoughtful touches—like the illuminated dial, high-filter switch, muting, contour mode, and robust speaker outputs—make operation intuitive and versatile. The rear heat sink and mesh guard enhance both cooling and visual appeal, while the solid wood cabinet delivers a uniquely Canadian aesthetic that sets this 630 apart from any other.

Pioneer SX-50 Silver Face Receiver – 50 WPC, Pre-Outs, 1983
Fifty watts a channel into 8 ohms at 0.007% distortion, and — unusually for a receiver this size — pre-out and main-in jacks on the back, so it can feed a subwoofer, take an equalizer in the loop, or hand off to a larger power amp. Introduced in 1983 with switchable CD and TV audio inputs, presets held by three AA cells, and the silver face of the decade that was ending. Graded Very Good.
Kenwood KR-A4070 Stereo Receiver – 60WPC, Phono, Original Remote
Sixty watts a channel into 8 ohms across the full band at 0.01% distortion, with an MM phono input at 2.5mV, a tape monitor loop, and separate bass, treble and balance. The original Kenwood remote is here, which is uncommon on a receiver of this age. Level 1 serviced; cosmetically graded Good, with honest wear for its years.
Sherwood S-7250 CP Stereo Receiver – 20WPC, Phono, Wood Cabinet
Twenty watts a channel into 8 ohms across the full 20 Hz to 20 kHz band, an MM phono input at 80 dB signal-to-noise, and a tape monitor loop. Sherwood built these in small runs in Chicago and sold them through the same shops that carried Marantz and McIntosh. Still in its original wood cabinet. Level 1 serviced here; condition Very Good.

Sherwood S-8250 CP AM/FM Stereo Receiver 25 WPC
Twenty-five watts a channel into 8 ohms from Sherwood's Certified Performance series — the range where Sherwood printed the measured figures for the individual unit rather than for the model. MM phono, noise filter, mute/mono, loudness and A/B speakers, behind a brushed aluminium face with walnut-grain side panels. Level 2 serviced here: bias and DC offset set, every control deoxidised.
JVC JR-S201 Receiver – 35 WPC, Japan, SEA EQ, Excellent
Thirty-five watts a channel at 0.01% distortion with a damping factor of 70 — numbers most larger receivers of 1978 could not reach. A five-band S.E.A. graphic equalizer sits on the front panel at 40, 250, 1k, 5k and 15kHz, alongside MM phono, two tape loops and push-button speaker terminals. Made in Japan, arrived professionally serviced; cosmetically graded Excellent.
