Need more info on the Electron Kinetics Eagle-7A

Hi all....just an update and again.....Thank you all for chiming in.
Sean you are correct with regard to my admiration for the Perreaux 3150B. If I can fix the two problems...this is the amp form my bass columns. It has the weights and control to offer a concert hall realism to music.
Now to some of your questions and some comments.

Yes, I do float the ground. I also tried direct into the wall and unfloating the groung.....still the problems.

As to the woofer columns and Kana's suggestion about pressing the woofer's to see if the noise appears.....that I will try. However, this "sneaker to gym floor noise", sort of a squeak, happens intermittently with or with any music playing. It also appears, for a second, when I turn on the amp. Then it goes away.

My biggest concern is that this does not happen whether 2150B is installed. So if it was a problem with the servo control on the Infinity, wouldn't it be doing the same problem with the 2150B???

Again, thanks all and Sean I will read up on your thread. I still would love to offer you a great Italian dinner to coax you over for a visit and "repair".......????

Rick- one final thought- if you have a multimeter, check the DC offset in the right channel of the 3150, If it's off(should be as close to 0 vdc as possible) or not stable(compare it to the left channel), it could be interacting with servo crossover to cause the your problem.

Sean- I haven't heard the Perreaux 2150B/3150, I'm sure
they are excellent amps.

Kana: That's a good suggestion about measuring the DC leakage. My brother did this after having problems with some speakers. What he found was that one amp was passing 3 volts of DC on one channel and 2.5 volts on the other. Luckily, this problem arose while he was running some junk speakers. Needless to say, that amp is out of the system until we can get it straightened out. 500 millivolts ( 1/2 a volt of DC ) is considered to be "acceptable" by most, but that is way high in my opinion. The amp that i gave my Brother to use measured less than .02 volts of DC on either channel.

As to the Perreaux's, the 2150's and 3150's are very similar amps ( cosmetically and in terms of basic circuitry ) that have very different sounds to them. I don't know anyone that has ever chosen a 2150 over a 3150 after hearing them side by side. Having said that, i run my 3150's strictly for woofers, as that is what they do best. Sean

Thanks Sean and Kana about the suggestion regarding DC leakage. However, don't you think the people that checked out the amp where I brought it would have checked it? Maybe not?!@?@!!!!

Anyway, I am a total incompitent when it comes to anything technical. Sean....my offer still holds!!!! (LOL)
