READ MORE ON OUR "HIFI REVIEWS" PAGE

110-240v Multivoltage. One of the RARE 1973 range of Trio-Kenwood Large Sized 4 Channel receivers that is Bridgeable to a very conservative 2x 50w, read on. Not all their 4ch Amps & Receivers are Bridgeable, this follows the same ideas as the Marantz 4070 4ch amp. This means it's a Proper Bridged amp with Inverting input into 4 channels with the Speaker Outputs altered by the rear 2ch/4ch switch. This switch you can use with the amp on & hear the doubled level of the Bridged Mode on Speakers. On Headphones it makes no Volume difference. UK version with the "Trio" name.

As a Stereo 2 channel amp this is as good as any 50w Receiver, interestingly lacking Filter Stages that can upset designs & today these Filters are of little use anyway.

 

FM plays stereo with ease, AM & Phono are working. The top row has lights for the Mode Switch functions: 2CH, RM, SQ, Discrete & Rarad which needs the optional adaptor that plugs in underneath. Lower row has Tuner signal & 2CH/4CH operation as per the rear switch.

Recapped & Upgraded, some New Transistors to remove Hiss. We Recapped the Power Supply, Power amps, Tone-Preamp, the Phono** stage & Relay stage. Didn't recap the 4ch Decoder Stage underneath or Tuner. The RM/SQ etc modes aren't in circuit until switched in & will give a simulated 4ch effect on 4 speakers if on 2ch it just phases the left channel to be quieter than the right. **Phono board in top half centre is now recapped, pic shows it as original.

Complex amp inside, but easy to use as 2ch & you get the benefit of Bridged Mode which gives more output than 50w suggests, see the Review page to see it's 39v 2ch Output is in the league of a 90w amp! 'Muting' button is FM Muting. For speakers it has decent Screws you can tighten without a screwdriver & a tab to hold the "Y" connector in place. The 4mm Gold Blocks aren't suitable here as spacing is tight. The screws are captive & spacing inside is tight so 4mm sockets would need altering to fit & a bit of a job on one let alone 16.

Sound of this is as good as the Sony STR-6055 we have, clean fresh sound with clean bass, not slow or wallowy. Biased up right this sounds Crisp & Runs Cool. High Grade condition as you can see & with the original 3-core Mains as fitted. Has a small chip on the lower front edge of the right side panel, looks like veneer if it's plastic wood-effect covering & the chip filled to look tidy.

A larger sized amp 555mm wide x 160mm high x 360mm deep if 410mm Max Depth inc fittings.

THE AMP ITSELF WEIGHS ABOUT 15KG
