Item specifics



Year: 1973
Format: Dual Quadraphonic / Stereophonic Made in: Cambridge, Mass. USA
KLH MODEL FIFTY-FOUR Dual Function Quadraphonic / Stereophonic Receiver

Made in Cambridge, Mass., USA in 1973.

This unit is fully functional with no distortion, no static nor any unwanted buzzing/snapping/humming sounds to speak of.  All lights and meters are in perfect working order.  

The ball bearing driven tuning wheel still glides the station indicator nearly all the way up or down the dial with a single spin. AND, REMARKABLY, the tuner itself pulls in more stations without an antennae than most of the newer tuners I've tested with an antennae hooked up. GOD'S HONEST TRUTH. 

This unit plays both quadraphonic and stereo recordings and has separate bass and treble sliders (a total of four) dedicated to each pair of speakers. It also has front and rear headphone outputs and a front/back/left/right joystick controller for precision control over each individual speaker's output. (Think of it as a combination balance and fader control.) In addition to the front and back speaker outs, there are also remote speaker outs. The F&B outs use standard speaker wire, but the remote outs require RCA style connections. (It's easy to adapt any speakers to RCA plugs, by the way).

There are 5 output modes: Mono, Stereo, Stereo 4, SQ4, and DISCR 4. 

It has two auxiliary lines in, a phono line, FM and AM. 

As I mentioned already, the FM tuner works better than most without an antennae. But it does have the traditional external AM and FM (300 or 75 ohm, as well as an RCA "FM Detector" output. I suppose I should mention it has a telescoping AM antennae for the potential bidder who still traverses the elder frequencies. (There is a small popping sound when weaker FM stations switch back and forth between stereo to mono when the muting button if off. But that's not a flaw. It's the nature of the beast with this unit. It's an audio indicator, so to speak.)

Since it is a quadrophonic unit, it has two pairs of ins and outs (front and back) for the tape lines, although only one pair (front) is required for stereo play and record. The phono line has traditional left right inputs only. 

There are two AC outputs, one switched and one un-switched. A great feature on older receivers are the fuse breakers. There are two main power breakers, one .2A 3AG and another 2.5A 3AG. Each speaker line also has a 3A 8AG breaker. So, if you want to test this beast's limits, and while doing so experience a speaker line suddenly cutting off; or, the entire unit shuts off altogether, don't sweat it ... you probably just blew a fuse. Just make sure to have some extra fuses on hand ... you can get them at any big box hardware or electronics store. 

Function controls include: Main Speakers on/off, FM Muting, Tape Monitor, Remote Speakers on/off, 2-channel / 4-channel amplifier mode, and Contour on/off. (Contour is like the later "loudness" button. It provides better fidelity at lower volumes - or at high volumes if you want to boost the lower/bass frequencies and your speakers - and neighbors - can handle it).

I don't have the detailed specs for this unit. All I can say is that it's an American-made, tube-amp power house that puts out lots of sound with a simple 1/8" turn of the volume knob. It's definitely high-end ... you can buy the specs from online vintage user's manual dealers.

Sorry about the high shipping, but this thing is heavy, and it will also require extra care (materials, time) in terms of packaging.
