Default Anyone else ever see the US made pyramid amps?

I remember back in 91 there was a small stereo shop in Huntington Beach, CA where I was living at the time. They had two white pyramid amplifiers that were made in the USA. Not just "designed" , but actually made here. I think I even saw some ads in my car audio subscription as well. They were white and resembled the phoenix gold MS series in the heat sink design. I couldn't afford one back then, but was very curious for a while, then basically forgot about them. I know pyramid makes so many cheesy amps nowadays, but I'm wondering if anyone else knows if any of these still exist. I would sure like to get my hands on one and see who was actually making them. Kind of like the premier amps pioneer made a few years ago that appeared to be US made by the way the internals and pcb were designed.

Default Pyramid/ Precision Power Amplifiers

PPI made High end Pyramid Amplifiers about the same time the Art Series amplifiers were being made. They were ordered by Pyramid. There were some contract problems and the amps did not reach the market in mass. These amps were in the Pyramid catalogs. They had the same model numbers as the PPI amplifiers. They were white powder coated. They were not overbuilt like the PPI amplifiers. PPI also built this style amp for G&S Designs and Black Max. The Pyramid amps were offered to me and my partner Paul. The only terms were that we could not market them in the USA. They did not want a lawsuit with Sound Around Electronics (Pyramid). We passed on the deal. We ended up buying the Lanzar PPI amps model 100 and 200. We also bought the Sedona 2 and 3 way crossovers for $21 and $22 each. These were the good old days. We did some crazy deals with Rockford also. These were the good old days.

I would definately like to find one of the "pyramid" ppi amps then. It would surely throw my friends off if they saw one in my car, haha. They know I like ppi, pg, orion, etc.. Plus, I would like to see the insides, for some reason I can't quite understand. Could you let me know if you ever hear about one?

Default Pyramid / PPI Amp

These were sold in the US - I remember seeing them at competitions. But they were hard to find given that Pyramid already had a flea-market image. This is similar to Jensen's little fling with their Nitro stuff in the mid 90's. The amps weren't bad, but their image was already destroyed by all those years of total junk.

I really hate eBay anymore. It used to be (around 1999-2001)that you could buy a cheap Pioneer CD player with no audio output [IOW - broken]for $5 plus $8 shipping. It's overrun with retail stores selling junk that nobody wants.

/\ Haha, wow that's one of them! Too bad I just bought a sony amp to fix and a hott set up for my friend on ebay. I'd like one just for the novelty of it. I'd actually run on of the 600 watt models in my car. That would really freak my friends and customers out ! They would never believe I had a pyramid running in my car. I'm going to tell my friends about that one and see if anyone will buy it. Its a little expensive for a 250 considering I won my A600.2 for a little over 150. Who knows, maybe after selling my borked punch amps I may have some $ to play with. Thanks for keeping an eye out for me!!

Default Soundstream 500s Repair help

Envision Electronics,
I saw your post a few times and am interested in your ability to fix stuff. LOL. Okay, seriously, I have an old SS 500s that simply won't turn on. I got it on ebay, not intending for it to be DOA. You posted in one place that if you had the parts, you could fix it and send it back within a week. But this was in regards to a PPI. Is that true for all amps? I would have emailed directly, but apparently I haven't posted enough material to be trusted with your email address. Makes sense.
Anyway, your thoughts or help is appreciated.
Bob

Back in a week, eh? That must have been a while ago when business was slower.

500s can have all kinds of problems. Typically, you've got dead MosFets in the power supply for one reason or another. Sometimes this is because the main toroid is shorted, the secondary common-mode coil has come unsoldered or the high current/voltage switch is bad. Of course, the Darlington output transistors could be shorted, shutting down the main supply.
I don't stock any of these components anymore, except some of the TIP output transistors. I don't think I have enough to actually complete a repair, though.
My basic rule for repairs these days is: You're going to wait for it. I work a full time job plus a side business that is going through some growing pains.
You might want to contact someone that does this full time if you're interested in getting the amp back in a week or two - with me, you might wait a month. I personally recommend Cecil "JustOneMoreAmp" here at this site and "onemoreamp" on the Phoenix Phorums forum site. He is as thorough as I am and comes with high praise from many "problem" cases.

Thanks for the leads. I didn't mean to make you nervous about the turnaround time, just trying to help date the thread. I guess I am questioning if I even want to fix this one with the challenges you mentioned. Thanks again.

To me, a really nice dead amp is like a life hanging in the balance at the ER. I don't care if I get paid to fix it or not - I just don't want to see it go to the landfill for a fairly benign (or very difficult) problem. I started repairing car amplifiers at age 17 (I'm 31 now) and never looked back. I can count on one hand the number of amps I couldn't figure out without a schematic. [Carver M-series, Yamaha (circa 1988) and an Xtant 1001D]. Everything else has successfully been returned to perfect health. I can't count how many repairs I've performed, but I know it's in the hundreds - all brands, shapes and sizes. I really like the super rare ones. I just (like 20 mins ago) bought a US Amps KA-200 built in 1989-90 before they had any distribution north of Alabama. Of course, it's broken but I've never seen one EVER. I can add it to my repertoire once it's back in action. I will probably refinish it as well, stripping the old anodize/dye finish and reanodizing.

As you can tell, I take my car amplifier repairs very seriously. If this 500s is in any good condition at all, it's worth repairing. You have to remember that the 500s was $900 new. A $75-100 repair is STILL worth the cost.

Didn't Crutchfield start selling the US amps? I remember hearing something about them years ago. They were okay or better than their price suggested..??
