Trio (Brand Name, Not a Model)

Name: Kenwood Trio
Brand: Kenwood

Before the badges said Kenwood, a lot of this gear left the factory wearing the name Trio - and the distinction still trips up buyers four decades later.

Overview

There is no Trio receiver. There is no Trio amplifier, no Trio tuner, no Trio turntable. Trio is a brand name - the mark that Kenwood used in certain markets, Japan and parts of Europe among them. Anyone hunting for "a Kenwood Trio" as though it were a single piece of equipment is chasing a phantom. The brand name tells you where the unit was sold, not what it does.

The name does show up on real, documented hardware. Period advertising from the late 1960s put the Trio/Kenwood badge on a solid-state AM/FM receiver built around a silicon power transistor, with five IF stages and four limiters, an automatic stereo/mono indicator, an illuminated pin-point tuning meter, and a patented blowout-proof automatic transistor protection circuit. It was rated at 30 watts music power, bundled with a matched set of speakers, and priced at $249.95 complete. HiFI-Stereo (March 1967, p.105) carried that copy, and the identical advertisement appeared in High Fidelity (February 1967, p.31). So the brand was buying space in more than one title in the same season with the same creative. High Fidelity (October 1967, p.98) went further and published measured tuner performance for a Kenwood unit, listing IHF sensitivity of 2.6 µV at 98 MHz, 3.0 µV at 90 MHz, and 2.5 µV at 106 MHz. Those are fringe-reception numbers, and the magazine measured them at three points across the band.

None of that tells a collector what a "Kenwood Trio" is worth, because "Kenwood Trio" can't be valued as a single thing. The Trio name sits on genuine equipment. Identify the actual model number stamped on the chassis and research that model on its own terms.

Key Features

Trio as a name carries no features of its own - no circuit topology, no spec sheet, no design lineage. The features belong to whatever model the badge is attached to, and the listings on the secondhand market show the range. A Kenwood Trio MC-60 desktop dynamic microphone with an 8-pin connector is amateur radio gear, not hi-fi. A pair of Kenwood Trio T14-0009-05 horn tweeters, pulled from a KL-7090, is speaker componentry. A Kenwood Trio DM-11 phono cartridge with an N-11 needle is a turntable consumable. That's three different product categories under one badge.

What the Badge Actually Tells You

Where the Trio mark appears, it identifies a market rather than a capability. The most concrete example in the documented record is the Kenwood TS-120V, an early-1980s entry-level low-power CW/SSB transceiver rated at 10 watts. One owner describes it as the same transceiver as the TS-120S but at 10 watts and built for the Japan market. A period test of the TS-120V ran in the Australian amateur radio magazine Amateur Radio Action in 1978, issue no. 9. That puts the model in the ham press rather than consumer audio titles, which is where Trio-badged amateur gear generally lived.

Rear-Panel and Power Details on the TS-120V

The TS-120V's rear panel carries an ANT (antenna) connector in UHF format, intended for a suitable antenna for both transmitting and receiving. Power is specified at DC 13.8V, and a dedicated DC power cable for the model turns up in the secondhand market. Accessories associated with the radio include the SP-120 speaker, the MC-50 microphone, and the PS-20 power supply. The PS-20 also appears paired with a DR-7500 in one listing. A replacement capacitor kit covering the TS-120, TS-120S, and TS-120V exists.

What the TS-120V Does Not Have

One owner's account of the TS-120V is blunt about the feature set: no memories, no filters, no lock button, no dual VFO. That is a stripped-down specification even by the standards of its era, so don't buy one expecting modern conveniences. The TS-120V was built as an entry point, and the missing features are the cost of that positioning.

Historical Context

The Trio name predates the Kenwood badge in the markets where it was used, and it lingered long enough that the two names still get conflated. The brand appeared on consumer audio in the 1960s, and the receiver advertised in 1967 is the clearest documented example. It was still showing up on amateur radio equipment into the early 1980s, when the TS-120V was sold in Japan under the Trio mark.

The documented record does not establish when the Trio name was introduced, when it was retired, or precisely which markets used it beyond Japan and parts of Europe. Collectors who need a firm date for a specific Trio-badged unit will have to work from the model number, not the brand name.

Collectibility & Value

Trio is a name rather than a product, so there is no Trio market to speak of. There are markets for the individual models that happen to wear the badge. The listings that surface under a "Kenwood Trio" search are a mixed bag: a Kenwood Trio MC-60 desktop dynamic microphone at $105, a pair of Kenwood Trio T14-0009-05 horn tweeters out of a KL-7090 at $42.46, a tested Kenwood Trio DM-11 cartridge with a good N-11 needle at $49.99, and a new-old-stock Kenwood Trio N35 diamond stylus at $4.75. Those are asking prices from individual listings with no date attached, not confirmed sale prices, so treat them as rough signals rather than valuations.

The TS-120V has its own small following among ham operators. One listing for a 10-watt CW/SSB transceiver described as junk and sold as-is carried a $198 asking price in November 2024, while working examples and bundled packages with the SP-120, MC-50, and PS-20 turn up periodically. A replacement capacitor kit covering the TS-120, TS-120S, and TS-120V is available, which matters if a unit is being bought to operate rather than to shelve.

For anyone encountering a Trio-badged piece, treat it as Kenwood gear from a different market, find the model number on the chassis, and value it on that model's merits.
