I like the velcro bundle ties. Changeable without destruction. But dust and pet hair tends to get stuck in them.

Where do you get "free" zip ties?

Agreed. They sound excellent, especially when dialed-in by the Chief himself. Who is the chief dialer'inn'er? that'd be Chief Bonehead I presume. He's rumored to work at Klipsch

If you have the time for eastward/inland excursion the Columbia River gorge is quite scenic.

Its odd from them to be on at all.

I got a nickel

If it is unbalanced connections(consumer equipment, RCA connectors) current always flows in the shield. Otherwise there is no circuit.

Again I know what? I don't think the OP's system is THAT complicated. How'd you know I am bald?

We still do not know what is causing the problem. And the OP doesn't seem to care about getting it fixed properly and seems content to live with a lifted ground. This lifted ground was not necessary before the lightning storm. These are the only facts we know. Unless I missed something. Wildly speculated denials? Huh? Whoa that's a Quantum Leap We do not know this. The OP never responded to my original question.

So its always been unstable at turnoff? How old was it when you got it? Now I'm really curious. I hope you do one or the other of DJK suggestions and report back.

Yep, that there is funny

I'm sorry. I looked up the data on transient suppressor XYZ and sure enough it always fails open or shorted. Open = 10 ohms or greater Short = 10 ohms or less Ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha, ha, ha,ha, ha, ha

A part cannot partially fail??? So nothing has ever been intermittent? It either works or it doesn't? Wait a minute I'm writing these facts down for future reference. When my boss is riding my azz about getting an intermittent problem here at work corrected I'll send him your way. What's your number?

Gotta love those "stealth" modifications.

Now you need some tractix midhorns from Fastlane also Or Eliptracs If you already did that I missed it, sorry.

"No and I don't know how you took that meaning from what I posted" Cal Blacksmith, I think it is from what you posted in post #2. It is somewhat ambiguous and more than just me didn't understand if you were expecting help from us here on the forum or if you had called Tech Support at Klipsch.

Any protector damaged by a surge was undersized and ineffective. Effective protectors work during microsecond currents. And remain functional after every surge. Any protector that 'sacrifices' itself is how near zero protectors are promoted to naive consumers. No effective protector protects by failing .. after a surge has done damage. If a protector is leaking current, then its protector part degrades quickly into a short circuit (blowing a fuse) or into an open circuit. Either way, it does not explain a ground loop. OP should identify the ground loop (A connected to B connected to C connected to A) before accusing one part only on speculation - ie a protector. I stand by my post as a POSSIBILITY. As in "if it happens it must be possible". IF there was a surge protector in circuit when the lightning strike occurred and now there is a hum problem it must be eliminated as a POSSIBILE cause of the NOW occurring problem. This is pretty standard troubleshooting protocol. JEESH.

Yea but the lightning strike could have partially damaged the surge protector devices in the power strip(if it has them), now causing a small current to flow to ground that was not flowing before the lightning strike. That is what they are there for, to get damaged instead of your expensive equipment. This is not rocket science but it is electrical engineering. Anyway that is why I wanted to know if the power strip had surge protection and if it did has the OP tried eliminating or replacing it.

I'll bet DJK will have a more definitive answer but it sounds like one or more stages in the amp is unstable (or becomes unstable) as the power rails are dropping and goes into oscillation.

Cal Blacksmith, you have been asking for help here on the forum? Or calling Klipsch Tech Support?

Have you tried eliminating the power strip? Or a new power strip? Does power strip have "overvoltage/surge protection"? I also find it very curious that you had no problem until there was a lightning storm and now you have a ground issue. Sorry for being late to this thread

Yes I did mean that exactly LOL And to this Question If I enter this code into my Z80 will i simulate a new universe? 4e 6f 20 62 75 74 20 69 74 20 69 73 20 66 75 6e 20 74 79 70 69 6e 67 20 69 6e 20 63 6f 64 65 20 69 66 20 49 20 77 61 6e 74 20 49 20 63 61 6e 20 73 61 79 20 74 68 65 20 77 6f 72 64 20 41 53 53 20 61 6e 64 20 69 74 20 77 6f 6e 27 74 20 67 65 74 20 46 6c 61 67 67 65 64 20 4c 4f 4c OMG its alive! Do you have the female version?

Jubs with grills? Maybe added by owner? Or its a clone?

This guy has a wonderful choice of custom made speakers and he has that crappy choice in wall hangings? :facepalm: OK fess up, who's are these? I gotta think its a forum member

Steve_S did you mean: 49 20 4C 6F 76 65 20 74 68 69 73 20 6F 75 74 20 6F 66 20 74 68 65 20 62 6F 78 20 74 68 69 6E 6B 69 6E 67 If I enter this code into my Z80 will i simulate a new universe?
