KLH Model 24 (circa 1966–67)
The KLH Model 24 turns up in listings under a dozen different names - “Radio-Phono Combination,” “Turntable Radio Wood Cabinet Record Player,” “Turntable/Tuner/Stereo Amplifier.” It is a mid-1960s all-in-one system: a record player, an FM stereo receiver, an amplifier, and a pair of matching wooden speakers. The record changer is a Garrard, and the system is rated at 40 watts. It was built in Cambridge, Massachusetts, in the United States, and period listings date it to 1966-67.
The speakers are marked as 8-ohm units. There was apparently a Series II revision. An ad showing the back view of the system’s speakers labels them “Model 24 Series II,” and collector discussion confirms two versions exist. The same discussion notes the input was via RCA plug. Radiomuseum describes the cabinet as a low-profile table model, big for its category. One PS Audio piece looked at the internal construction with the grille off and noted that KLH saw no reason to make everything square and parallel when nobody was going to see it.
The speaker side of the system is hard to pin down. One reseller claims the Model 24 “promises an immersive and high-quality audio experience” thanks to its “24 speakers.” That appears to be a misreading of the model number, not a driver count. No reliable frequency response, crossover, driver count, or dimensions have surfaced. A schematic reportedly exists at thecodemachine.co.uk, but the details haven’t been transcribed anywhere public. No original price is documented either.
The Model 24 was clearly sold as a complete package of turntable, tuner, amp, and speakers, but it has left a thin paper trail. What survives is mostly the hardware itself: eBay listings show units sold as parts or restoration projects, a Craigslist pair of Series II bookshelf speakers, and a Reverb listing for a “1970’s” tweeter. That date conflicts with the 1966-67 dating, so it is probably worth ignoring unless a serial number or better source settles it. One collector on YouTube shows the FM stereo version with its Garrard changer and matching speakers still working.
