That may be possable If you are ever in the DC. area you are more than welcome to stop by!!!! I may go to the NY. Meet. and it looks like we might have a DC. meet soon.

I too need to find someone to "go through" mine, as I would like to grow old with it. (where do I start as far as finding someone to work on mine?) .

I tried to sell mine also, it is still mine.

Nice looking on the outside!

There were plenty of pictures of the insides of the toasters. Much
discussion on the wiring job may have been suppressed or deleted.
But some discussion did survive. The biggest issue that people are
finally finding out is that it does not have to be built like that to
sound good.

Some people needed to keep up the illusion so that they could dump
their units without taking too much of a bath.

But the biggest problem was rampant fanboyism.

The people that now own SP amps are the ones that really like them
and will do whatever is necessary to get them fixed. This is a good
thing. In the long run these amps in the future will start increasing
in price.

Maybe someone will even build and sell extremes built correctly.
There may be a market for amps like this in the $2k to $3k range.
Definitely not a market for ppx/mpx like things in my opinion.

The answer is simple. Most people didn't or better yet, couldn't open their amps and see the craftsmanship.

I asked Mikhail 5 times to show me pictures of what my Maestro looked like inside, and he put me off, giving me varying excuses.

I know for sure that in 5/5 of the SP amps I owned, all were very well constructed with high quality parts. What great luck.

Yes, no one could open their cases for seven years. That must be it.

Yes, the wiring on the toaster I owned--as well as an MPX3 in the final casework-- was not as ordered as I am accustomed to--but--that is of NO SIGNIFICANCE--none whatsoever with respect to tone or safety. Must be other wiring issues that were deleted--though I never heard of them.

The situation is not so simple--not by any means at all. But, at a certain point, one begins to 'get it' and moves on. This thread is not the place for positive points on SP. Sorry. Wrong number.

Thanks, though, for taking trouble to respond. Much appreciated, as always.

Maybe after i'm done with the T2 and SRX2 i'll do a diy balanced extreme board.
Trouble is with the teflon sockets and either dact or rk50, its not going to be
cheap to assemble. Plus chassis and real power supply, it could get to $4k in
parts real easy.

I'd like see the power supply for that beast.

Here are some photos of a Platinum Extreme sent to me.

This one was built on a MPX board.



The light blue cap in the middle is the smoothing cap for the filament supply. Does it look like it may have been under some stress?

BTW, filament voltage was measured at 4.0.



Other side of the board.



It may be hard to see at this resolution but the solder joint has gotten so hot that the solder has flowed out of the connection.

This unit has a Plitron transformer, but as Dr. Gilmore mentioned earlier, it is the wrong one for use in an Extreme. I have discussed this unit with it's owner. It will be gutted and the Extreme circuit built point to point. The transformer will be replaced with an Electraprint custom built one.

Here is my favorite shot from the Singlepower units sent to me for evaluation.



This is the tubed, external power supply for a Concerto ES-1 (combination of a Maestro dynamic amp and ES-1 electrostatic amp).

Nasty, un-called for remark. There are 2 ways of saying anything.

Obviously, anyone who has owned 5 amps from the same company is going to defend it to it's death if they didn't have any problems. But the fact remains that Singlepower made it nearly impossible for the non-technical to open their amps.

Now why would that be, I wonder?

And i thought the cap soldered to paper clips was bad.
That thing is pretty much unrepairable.
If its the tubed power supply, it was something over $7.5K originally...

Maybe it is time to start on that diy balanced extreme board...

I have it!!!!

I wish I had a better picture. Aaron, it "was" a bitch to open. [size=large]Kevin can I send this one to you???[/size]

Quote:



But they sound so good!

pics or ban!!!

Quote:



please, not before the T2 words cannot describe how interested i am in the whole kit and kaboodle for that one


edit: i see you mentioned you are still working on it earlier. hooray!

How about an unbalanced board? I would buy one for sure.

Hi Dr. Gilmore, as the owner of an MPX3 would you please expand on this? Thanks.
