It may be worth more than $30 though. I had a KLH 27 receiver once that I threw on eBay and it ended up selling for over $200. Seems some of the KLH stuff is collectable and quite rare.

The KLH 27 is a Henry Kloss design.
It uses the vernier dial tuning that he used with KLH, Advent and Tivioli radios.
It is a collectible.

The KLH 51 is from the Singer (as in sewing machines) era.
The last (2) units on ebay received (0) bids.
Is is not a collectible (at this time).

Hey eThink, that was my KLH 27. I took that picture for my eBay ad. Nice looking unit huh?

I got it for $12 with the intent of keeping and listening. Cleaned up well, no missing knobs, sounds perfect, all lights work, couldn't be happier.

I have heard that the KLH Fifty One used tubes and transistors.
I would be interested in "nude" pictures of this unit.

The 51 is all ss. It was sort of a one off visual design from the other KLH models of the time. Almost as if KLH could not figure out where to go with the looks. In sonics, I think like most of the KLH and Scott ss units it is better sounding than most of the Japanese branded units. I suspect they were tuned to be a crossover between the ss and tube sound and a bit more like what the US market at the time still seemed to prefer. Actually, it had embraced the harsh ss sound by this time but the American companies still had not realized that we were moving towards a differing sonic perspective than in the tube days - well the mass market anyways.

Based on my research, there were three "generations" of design for KLH receivers from 1965 thru 1980:

1st Generation: the 'Henry Kloss' era:

The Model Twenty Seven was the only receiver of this era.
It's twin vernier tuning dials are a common theme of Henry Kloss designs. These units were manufactured in the US in the late 1960s.

2nd Generation: the "Singer" era:

The Model Fifty One was the only receiver of this era.
It's design is unique to this model. Linear Tuning Dial, metal and wood case. These units were manufactured in Japan in the early 1970s.

3rd Generation: the "Kyocera" era:

Multiple models ranging including 50, 52, 52A (Quad), 54, 55, 57, as well as the 71 and 72. These units had very conventional (bland) styling for the era: Black-out, linear tuning dial, silver face, rotary controls, and push button switches. These units were manufactured by Kyocera in Japan in the mid to late 1970s.

I have liked the unique design of the KLH Fifty-One since I first saw it in summer of 1972 at Sam Goody's on 3rd Avenue in NYC.

$239 was a lot of money (for me) in 1972!

I have not owned this receiver (yet) :)

As Gomer would say, "Surprise, surprise, surprise". Somebody doesn't like their's as much as I like mine.

If anyone has a lead (or copy) of the owners manual for this unit, I'd be eternally grateful for a copy.
