Post Number: 1 Registered: Sep-04	Posted on Tuesday, September 14, 2004 - 19:16 GMT Minor issue, more a mystery/minor annoyance--no show stopper. Here's the deal:...Vintage tube receiver (Harmon Kardon, circa 1962 and it works very well and can rocks the room!).... The left channel has an occasional "snap, crackle or pop"---just like playing an LP a few scratches on it (remember those?) It's not all the time, but every once in awhile. I've checked tubes on a meter (other than occasional gas, most are fine), I've switched around the tubes, checked the switches/pots (volume knob, balance, etc--no luck), switched around the speakers....basically all the obvious things. Is this perhaps a sign of a bad capacitor or resistor for this left channel? No big deal, just has me guessing. Thanks in advance for any help you can offer.

Next take the top of the receiver off, and blow out all the dust. Last you need to buy a can of contact cleaner, such as caig. They make good contact cleaner so visit www.caig.com and take a look, and once you buy some electric contact cleaner- spray the cleaner in switches & pots and work it in by adjusting each switch & pot at least 10 times. Make sure you unplug your HK and let it dry for at least 24 hours.
