New version: Posted Sept. 28, 2012.

Please disregard the old versions in the Library. There are some inaccuracies in those (and if you find any inaccuracies in this version please let me know)

Includes info in the KLH Thirteen, too.

 

edit: a sharp-eyed reader noticed the following goofs. Thanks Jon!

Page 6, radiodaze link is dead. (they no longer sell Plas-T-Pair)

Page 9, howardproducts link is dead. (should be http://www.howardpro...or-a-finish.php  )

Page 10, charlescraft link is dead. Michael's stopped selling this for a while. It seems to be available now, but it is no longer made in Ireland--it's made in Poland. Try

http://www.shopdmc.c...?CID=90&IID=925

Page 14, justradios.com link does work for me: try http://www.justradios.com

Page 16, for 1 amp, 1kv diode, how about 1N4007? any diode rated above 0.2A and 400V will do. Size 1N4007 is a good cheap all-purpose 1A diode, or the 1N5399 1.5A.

Page 19, fifth paragraph, “…is 27000 ohms (2.7K)…” should read “…27,000 ohms (27K)…”

 

Here's an important one:

Page 19, "A 0.047mF cap was added across the switch terminals as an arc suppressor." WARNING! The suppressor cap must be rated for 250v AC

 

and thanks to John O'Hanlon for this one:

Page 20: Regardless what the schematic says, the resistor connected to the NE-2 neon lamp should be 100K, NOT 68K (this is probably something KLH caught mid-production and may have addressed in a service bulletin. Anyone who wants the technical explanation PM me or wait for Rev 5 in 2014).

Hi Kent

I have never owned or heard a KLH radio.

I always read good things about them, outstanding sound but expensive.

You did a super job, Kent, very well done.

Here it is: The original 12-page typewritten instruction booklet for the Model Thirteen. I scanned the pages revshot sent, used OCR, then went through to correct spelling etc. The resulting document, in Courier font, looks pretty much exactly like the original. A bit long-winded, but stereo FM was new at the time.

Please let me know if you find any typos.

Kent

a couple of typos corrected 5/5/2011

Here is a great place for tubes, speaker cloth, nobs etc.

If it doesn't matter the brand of capacitor I have always favored Vishay / Sprague "orange drops"

Thanks Trans. If you read my manual you'll see I provide a link to Antique Electronic Supply (tubesandmore.com) on page 5.
Working on a minor revision now, so any input is welcome!

The latest version is here. See Post #1 (and disregard the old versions in the Library).
Thanks, Gene for shrinking it down to manageable size.
