Good discussion guys. Since I got this hum with the new subs I've been picking the brains of everyone I can about cheater plugs. Most I have talked to have said the same thing... They've been using them for years on end (20 to 30) and never had an issue. BUT and this is a big but, there is always the risk of what Gorilla Killer mentioned above. However, no one I've talked to has said they have ever heard of or read about someone getting electrocuted due to a cheater plug (but that doesn't mean it hasn't happened). My question is: if you need to adjust something on the sub amp why not unplug the unit first to kill the current?
Anyway, its obvious that using a cheater plug can be dangerous but the odds seem low. However, you will be rolling the dice so everyone must make that decision well informed. On another note the discussion of fire breaking out came up. Now that's the one that scares me more than the risk of shock. I used to work for an a major insurance company as a fire underwriter, believe me they will find any excuse to not cover a claim. But fire seems even less likely than getting shocked. But it too is a possibility so keep that in mind. My solution to that is to unplug anything that is using cheater plug when I'm not in close proximity and not using. I can put out a small fire I'm near and aware of... its the one that breaks out in the middle of the night or if I'm away from home that scares me.
The worst part of all this is the makers of the amps could solve this problem if they took the time to track down the source of the hum in their amp. How do I know this? Well, my V3601's had a three prong plug on them and never once did it create a hum. It's not a matter of how much power the amp puts out its how well its insulated and wired and designed etc. Don't get me wrong, the amp could be top notch but if they are not concerned about tracking down potential ground loop hums then they will not address the problem. After all, it's not really a big deal to the amp manufacturer because it affects some and not others due to all the variables involved. But they could negate the issue if they wanted to... just food for thought.
On another note, I've isolated my ground loop hum to two issues... the blu-ray player and the satellite TV. They are both 50/50, disconnect either one and you it cuts the hum in half. Disconnect both and the problem goes away. Now I need to decide on how to deal with them.
But what I really need even more than that is for Jeff to call me back and fix my dead amp issue. I really want to have two working 2400ULF's. I hope he get's back from vacation soon. Does anyone know his plans by any chance?
