The KLH Model Eleven "suitcase" stereo went into production around 1965, I believe. I have one in the corner of the living room in flawless, working condition with original manual, original speaker and power cords (the power cord uses a strange connector and it's very hard to find another one so if you have one, don't lose it!).. anyway I don't use mine, it's just kind of collecting dust, but I've owned it since the 1970s and it still works perfectly
The Model Eleven was made in a few different incarnations:
- the gray three-piece suitcase model
- the same model but covered in white vinyl instead of gray
- in a three-piece walnut model called the Model Eleven-W
- in a variation with an AM or FM tunng dial (or both, I forget)..
They were all basically variations on the same theme. I am a HUGE fan of the Henry Kloss-era KLH stereos and radios.. I also own a KLH Model Twenty-One FM table radio (an absolute classic) which I bought for myself as a birthday present brand new for about $80.00 in 1967.. I used it for decades but decided to preserve, although it works perfectly, and being a packrat, I kept its original box, instructions, warranty card, inspection slip, and have it tucked away in a closet.. they are common on eBay, some in excellent states of preservation and some quite beat up.. mine is close to perfect but since I don't use it any more, I decided to put it back in its box to preserve it.. just try to find one on eBay with all the original packaging and inserts
Besides the Model Eleven suitcase stereo, and the Model Twenty one FM table radio, (which are both "resting").. I also have a KLH Model Twenty stereo system with original Model Twenty speakers.. this was KLH's top of the line stereo back around 1967 when it sold for $500.00.. when I bought my KLH radio I drooled all over a Model Twenty at the same music store (remember music stores that sold records, sheet music, radios, and stereos?).. it's the much bigger brother of the Model Eleven which had 10 watts per channel.. in between them was the Model Twenty Four with, I think, 20 or 24 watts per channel, and then the Model Twenty top of the line with 50 watts per channel and huge walnut speakers with 10" woofers. Here's a picture of my KLH Model Twenty system, well, most of it:
Sitting atop its left-hand speaker is one of a pair of Micro-Acoustics MS-1 MicroStatic "super tweeters" I picked up this whole system from three different sellers off eBay over the last couple of years.. those "super tweeters" are wired in series with the Model Twenty's main speakers.. between the speaker (one of a pair) and the console (which has the optional fancy wood and plexiglas lid).. is a circa 1979 Pioneer CTF-900 three head cassette deck, also in Mint condition.. from Pioneer's "Silver Age" classic period of the late 1970s.. sometime in the early 1980s, the Silver look went out, the quality went down, CDs came in in 1982, most stereo mfg. switched from Japan to China, and that was that.. depsite the age of my Model Twenty system, it sounds absolutely incredible..
Sometime last year I went on a frenzied search and collected as many pictures of KLH audio equipment I could find, and here it is and you're welcome to it.. you'll find pictures of all the variants of the KLH Model Eleven (or "11") in it.. along with their other 1960s models of radios and compact stereos.. no I don't own all of this equipment, just the stuff I explained above, so these pictures came from many sources - eBay auctions, and many Web sites.. but you'll see just about everything KLH ever made while Kloss was running the company..
Generally speaking, the older ones have the beige plastic knobs, which then morphed into silvery knobs a few years later.. then they started making the ugly stuff and Henry Kloss bailed and started his next company, Advent.. there should be some good history sites about Kloss but basically, the companies he founded and ran before he passed away a few years ago were Acoustic Research (AR), KLH, Advent, and Cambridge Soundworks..
He was the Grand Old Man of the "East Coast" HiFi mfrs., an absolute genius when it came to audio equipment design, and a huge proponent of acoustic suspension speaker systems, which all his vintage equipment has.. I have a nice pile of original KLH sales brochures, owners manuals, all that stuff..
I could talk about this stuff all day but I'll shut up for now
