Buzzing in KLH R7000

I have a shipping damaged KLH R7000 receiver that has a 60 hertz buzz in the speakers. The buzz does is always present and varies only slightly with the volume level. Everything works on the system. The repair shop said the trouble is related to a bad voltage requlator, which blows a capacitor that is supposed to filter out the buzz. They say that the voltage requlator would only be available from the manufacturer, and therefore would be very expensive. I don't work directly in the electronics field, but it seems to me that a voltage regulator would be a somewhat generic component that should be available from a number of sources.

It has power but it clicks off

First thing to check is theat there is no shorts in your speaker cabling either damaged cabling or ends toching together at the amp or speaker connections.
If there is notheing tounching, try unplugginging ALL of the speaker wires then start it up again, if it doesn't click off then carefully check all of your speaker connections. try plugging them in one at a time while turning it on and seeing if it clicks off.

If it isn't a problem you might have a problem in the power supply or amplifier modules of your reciever - That problem would be one for the pros!
Hope this helps!
Good Luck!

I own a KLH R7000 receiver and need to know what kinda fuse i need to replace mine? thanks for your help.

Take the top cover off with the unit unplugged, you will see the fuse just beside the big capacitors, diodes and the power transformer(and fuse current rating is written on the board) . The problem with your receiver is worse than a fuse I suspect. So, before replacing the fuse check for short circuit. If there is a short circuit specially power amp section(which is common to fail) the problem might get worse when you rplace the fuse without checking it. :)

Audio receiver!

When I watch movies, most of the talking is directed to the center speaker. During surround sound, this gives a more realistic environment, with voices coming from the source (center where your tv is) and ambeint noise coming from the left/right corners.

Get a small center speaker to solve your problem.

Klh r7000 no sound

Like I wrote, I had a similar problem with popping and then no audio for an extended period of time. I found the solution on another site,

Apparently the solder joints are weak, and just as the blog described when I opened up the receiver I saw the same scorch marks from overheating. Just as the blog described, I added solder to each of the joints in the photo and have had no problem ever since.

I am no solder expert, this is my 2nd time, but all I did is build up each of the joints and I have been listening to music, playing movies in surround sound with no problems, no popping for the last 2 weeks.

Technics sax-710 receiver Nht sb-1 speaker developed a buzzing sound when playing, Kids may have over drove speakers(not sure) Replaced with nht supezeros now both speakers sound very staticy like off...

The speakers have buzzing sound because of damaged cones.
Over driving speakers, especially with heavy low frequencies, can tear the voice coil away from the cone.
Once damaged, only replacement will help
