Thanks for taking the time Nate.

Apparently (after some detective work) my MPX3 is an early
(probably 2004) P2P model. It had two previous owners before me.
No issues have been reported by those owners and I trust their word.

I need to get the amp inspected by a competent technician.
Not an easy prospect here in the UK but I've found several
candidates that are looking good.

I'll update the relevant threads here when I have some info.

Cheers Nate

I just wanna say that it doesn't mean anything really. An amp can fail at any given moment. My Extreme was issue free through two previous owners, but it crapped out on me one day.

There are some serious problems. No doubt about that.

But, life-threatening issues aside, alot of SP amps really
do sound very very good. They would not have gained
such a reputation otherwise, and I really don't think it's a case
of the Emperor's new clothes.

People need to get their amps checked by a professional
and go from there.
NO..... People need to GET THEIR AMPS period..........don't endorse this piece of **** company in any way any longer..... I can't stand it.......Single Power is a FRAUD company.

EDIT: My anger is not directed at you sorry, but I am just so sick of all these Single Power threads. Mikhail Rotenberg stole thousands from me, and left me with no amp and damaged other equipment. He is both a con man and an incompetent engineer/builder. He needs to be put out of business, and people should no longer condone anything about this man's business......even if you think your amp sounds great, keep it to yourself please because there's no future for buying a Single Power amp.......at this point, I would rather have $9000 stolen from me than risk my house and my life by using a potential bomb as an amp.

WE NEED TO COME TOGETHER AS A COMMUNITY AND MAKE A TRIP OUT TO MIKHAIL'S FACTORY / RESIDENCE AND CONFRONT HIM ON HIS UNLAWFUL BUSINESS PRACTICE AND UNLAWFUL PRODUCT SPECIFICATIONS....... I tried to start a thread filing a class action lawsuit and for some reason this thread was shut down. But I have not given up.

Thanks for doing this Nate.

That's silly. I'd be upset too if I lost money, and I'm not happy my amp may need to go to a tech to be checked out, but it sounds great, and many of us will probably keep our amps, either as is, or after we have them checked out. None of this excuses what Mikhail did, but we need to have a little bit of rationality here.

I don't think anything I said was irrational.........the only reason to continue to endorse Mikhail's product in any way would be to endorse his business......this should not be......if you are happy with your amp that is great, cause you are lucky, but it is a sensitive subject for me and many others and I don't want his business to continue.

Hmmm, seriously..... "as is"? after all of these unstable configuations, unprofessional work, under-spec components (nevermind about transformers, I mean a 50v switch for 520v and 220v voltage control?) and people can keep their amps... as is(are)?

That's same thing as let that time bomb as is. People are really so fearless against high voltage and exploding caps...

That's pretty much disservice to themselves if they let these faulty amps alone. And people should be discouraged from trading amps containing potential hazard, unless they have gone extensive repair and reworks done.

Someone saying their amp sounds good is not endorsing Mikhail's product or Mikhail. It's saying the amp sounds good. And his business is not going to continue. Too many people know about him now.

My amp has worked fine for 5 years, and many others have had their early SP amps for a long time. The number of catastrophic incidents is very low at this point, and not every amp is rife with the issues you raised. I've read this thread and others carefully, and assessed the risk, and while I will probably get mine checked out, it's up to the individual to decide whether to use his amp "as is" for a time.

Let's keep people informed of the facts, and let them make their own decision.

If you can safely access the inside of your Extreme there's a good chance that we could tell how the trafo is wired and if it's the same under-spec'd Hammond. I wouldn't trust shining a light through the trafo enclosure if it were my amp and had that little trafo box on it. You can see in the picture that Kevin Gilmore posted in the other SP thread what an Extreme with a properly spec'd trafo looks like. The transformer in that picture (a custom Electraprint) weighs more than the entire original Extreme did.
I posted high res pictures here and would appreciate it if you could take a quick look. Let me know if you need more detailed shots of certain sections.

Great, so as someone said earlier in original thread, rolling the dice for one's life....

This should probably be stickied. Good work Nate.

Yeah, it is a paradox that such a good sounding series of amps could be so incredibly dangerous and badly designed. However, everyone must get used to the fact that an amp that's got serious safety issues can still sound good. Safety generally means that it's just going to fail way, way sooner than it should because its parts are misused, potentially maiming its owner in the process. It's like the three little pigs...the straw house is a perfectly working house by all appearances, but the wolf has no trouble blowing it down.
post #28 of 407
Hopefully David's plan will come to fruition as more and more people realize that their amp is actually dangerous and not fit for use or trade. Fixing its misspecced parts is a good call, but it seems that the amp's overall design may have problems too, maybe there are some unfixable things. Everyone that's within a day's drive from Colorado should meet up to confront him. I'm still amazed nobody has driven to his house to talk to him face to face.

Yeah, let's use hyperbole as much as possible. That's helpful.
