KLH Model Twenty (1966–1968)
The KLH Model Twenty is a solid-state stereo receiver with an FM/AM tuner, produced from 1966 to 1968. It's a hybrid. The amplifier section uses silicon transistors, while the tuner section keeps a tube front end. The chassis is compact and low-profile, with a brushed aluminum front panel, a backlit dial, and a "Stereo" indicator lamp for FM stereo reception. Controls include a selector switch, volume, bass, treble, balance, and tuning knob. There are also two sets of speaker terminals, a headphone jack, and a DIN-type tape input/output.
The receiver was introduced as a companion to the KLH Model Twenty speaker system, and the pairing was marketed as a compact component system. KLH also offered an optional Model 20 speaker pair as a matching setup. According to Vintage Knob, the receiver sits above the KLH Model Seventeen in the lineup. The Model Twenty was part of KLH's early solid-state receiver lineup, designed for low-cost, quality home audio.
High Fidelity (February 1967, p.27) ran an ad introducing the Model Twenty as a "high-performance stereo music system," noting that its features were exactly what most people had in mind when they walked into a store — a period nod to its straightforward, practical appeal.
Documented specs are limited. HiFi Engine lists 20W per channel into 8Ω, frequency response of 20Hz-20kHz, phono input sensitivity of 1.0mV (MM), speaker load impedance of 4-16Ω, dimensions of 370 × 140 × 300mm, and a weight of 10.1kg. Vintage Knob lists a higher output figure of 30W and a price of $350, while HiFi Engine shows $275. The two sources conflict on both points, so treat those numbers with caution. No THD, S/N ratio, damping factor, or FM sensitivity figures are documented in the available record.
