KLH Model 20 Plus

I am looking for the owner's manual for the KLH Model 20 PLUS. Does anyone out there have one?

By the way, thank you very much for the schematic - I have been looking for that for some time.

re: Twenty

Thank you very much. I have been searching for a readable scan of this for a long time. I have the AM/FM version of the KLH Model 20 and documentation is almost non-existent.

re: Twenty

re: Twenty

Do you know where I could get the KLH model 20 regular manual? Not the schematic manual.

re: KLH Model Twenty paperwork

I bought a Model Twenty complete with consecutively numbered matching speakers today, which included the User Manual, salesman's brochure; instructions for installing the optional dust cover; instructions for ''using the stylus gauge"; and instructions for "Setting up the Model Twenty."

When I get my crap together, I will scan all this stuff and share it here. :)

Hopefully - sooner rather than later. :)

re: KLH Model Twenty paperwork

please do, i just bought a beautiful one that has a bum left channel. i'm still not sure what all the bells and whistles do...
thanks in advance!
update: i opened it up and found a few surprises. most of the wiring is crimped to pins on the board, and most of these were loose, a couple completely detached. i went through and tightened them all, and that fixed the bum left channel. i also had an issue with the treble pot becoming un-ganged, so that turning the knob only adjusted one side. i found out i could adjust the other side by turning the nylon slot in the bottom, and that by applying pressure from the bottom, both would turn together. after some consideration, i macgyvered something with a rod cap and a metal hole plug that would keep pressure on the nylon bottom while still allowing it to turn.

Just remember to have the units serviced, because after 50 years the whole system has age related deterioration now.
The main unit - amp needs capacitors etc, the changer needs overhaulling and new lubrication, new rubber, along with the new stylus.
The speakers - lose their suspension seals, and need recoating.

Of the several that came into my shop, ALL were in need of service, and I'm sure yours will be no exception - unless of course it has recently been properly serviced.

re: KLH Model Twenty paperwork

oddly enough, mine doesn't appear to have been serviced in ages, yet performs like a champ. it does give me a womp-womp sound when i turn it up loud, and i'm guessing that's the 2 big orange capacitors, although they don't appear to be leaking. any help with what to replace them with would be appreciated. i may look into recapping the speakers, but i'm not sure it's necessary.
