Just Found some new old equipment!!!

Just Found some new old equipment!!! (I have some questions)

I found a Harmon Kardon HK 340 amplifier and the KLH Model 20 sound system with speakers, receiver, amplifier, and turntable(the receiver, amplifier, and turntable are built in to the amplifier base).

I don't think the amplifier for the KLH works because it might not be outputting any sound.

The KLH Model Twenty speakers are amazing (they're the only vintage speakers i've heard though), and can even be compared to the speakers in my 5,000 dollar sony home theater speaker system.

The HK 340 is a good amplifier but the right channel doesn't work well (its fuzzy and crackly and buzzy).

Should i get a new amplifier or try to fix the two that i currently have? If I decide to fix one of them, which one is a better amp?

I have a multimiter that I can use to troubleshoot the channels if anyone is wiling to help me.

The h/k may just need a real good cleaning with some deoxit. Try that before giving up on it. Read the posting on DC offset as well.

Sounds like classic dirty switches and pots on the 340. An easy fix.

Thanks. Could you point me to a how-to guide for cleaning the switches and pots? I don't even know where they are.

The service manual can be found at:
http://manuals.harman.com/hk/Service Manual/hk340 sm.pdf

A pot is a control, i.e. volume, balance, etc. A switch is either rotary, like the function switch (phono, AM, FM), or a pushbutton, like the loudness control.

If you need any further advice, just ask.
