JBL 2230 (1975–1979)
The JBL 2230 is a 30-watt-per-channel stereo receiver that JBL produced from 1975 to 1979, and it holds a notable distinction: it was reportedly the best-selling receiver JBL ever made. That's a meaningful claim for a company far better known for its loudspeakers than its electronics. The 2230 sat near the bottom of JBL's receiver lineup, positioned between the 26-watt 2200 and the 60-watt 2250, and it shared the family with the 2265 and 2285. It was, in the words of one owner, the little brother to the 2250.
The receiver was built around a full complementary-symmetry direct-coupled amplifier stage with all-silicon transistors, and it used a large toroidal transformer — a component choice that was more common in premium gear of the era than in budget receivers. It included Dolby FM noise reduction, a feature that made sense for the mid-1970s when Dolby-encoded FM broadcasts were being tested, and the tuner section used a FET front end with a phase-locked loop multiplex decoder. The phono inputs were designed for moving magnet cartridges. The cabinet was walnut with a wood-grained metal cover.
The record shows some conflicting details on price and a few specs depending on the source. Original US price is listed as both $329 and $379 in different references, and frequency response figures vary slightly — one source says 30–30,000 Hz (+0/–0.5 dB), another 25–35,000 Hz (±0.5 dB). The most commonly cited figure for the power output is 30 watts RMS per channel into 8 ohms, 20–20,000 Hz, both channels driven, at 0.1% THD, with a damping factor of 30:1. Input sensitivity for phono is listed as either 1.9 mV or 2.0 mV into 50kΩ, and aux inputs at 150 or 160 mV into 100kΩ. Tone controls were ±12 dB at 50 Hz (bass) and 10 kHz (treble), with a loudness contour of +8 dB at 50 Hz and +3 dB at 10 kHz. Signal-to-noise was 68 dB on phono and 80 dB on aux/tape. It weighed 25 lbs and measured roughly 16.8 by 5.35 by 12.4 inches.
Owner reports over the years have been consistent about the sound character: warm and smooth, with a clear midrange and enough power for most home listening situations. It's not a powerhouse — one owner noted that driving inefficient speakers will expose its limitations — but paired with efficient JBL speakers like the L100, it was a well-matched combination. Several owners report using theirs for twenty years straight with nothing more than a tuning capacitor cleaning. Common issues are the usual vintage receiver complaints: scratchy volume controls (DeoxIT fixes it), dial lamps that need replacing (LED kits are available), and 40-year-old power supply capacitors that should be replaced.

Collection prices have climbed in recent years. One owner reports buying one at a garage sale for $25; another notes seeing them listed on eBay in the $200–400 range in 2023–2024, with one seller asking $550. These are asking prices, not confirmed sales, but they reflect the 2230's growing scarcity and collectibility.
