Nobody fishing for amps? What are these Monolithic MSI, someone on another site posted about them on epay 120616864577
I've only seen a couple of these but both had badly warped boards. They boards are used to clamp the transistors and over time they become warped. When replacing the transistors, they aren't clamped well and it takes a bit of effort to get the transistors properly clamped.
Thanks Perry, that sure looks old school, maybe shades of SS or LP. The guy sure has a stout price on them, though I've never even heard of one before. TO3 outputs...I don't see the PS transistors?
I see it. Oh is that a screw there to clamp them? Ok I got it sort of like SS does. I so wish some amps didn't make it so difficult. I have about 4 spring clamps I have to re-bend for an infinity, the last model they use the double angles that slide in they were so nice.
So I assume they were a premium amp back in the day?

The screw is to clamp them but there aren't enough screws to clamp it properly.
I don't know if they were considered a premium amp. The amp may be OK audibly but mechanically, they're a disaster.

Holy crap that's a messy amp, I remember the brand popping up but they didn't seem to thrive. On another note I got an adcom 5450 (not super old school) recently and its built very well even to today's standards. The power supply has been repaired but it seems to play fine. I won't really know until it gets installed in my project car.
Hey look at this BRAND NEW In Box Phase Linear PLA200 300 Watt Car Amplifier
Anyone in South Jersey, is that really made in USA....by who? Phase Linear, I thought they were always Taiwan or something.
Far as that MSI amp, I really don't like it when they do strange stuff. I mean a board is made for electronics mounting not clamping things. Transistors are not made to hold the board in the amp (in some newer amps), I don't see what real advantage they see in screwing things together half baked or backwards that way. I guess I can see why they would not screw it at all, they can buy less screws that way.

I own a 15 years old ZAPCO Studio 500 used to drive (in bridged mode) my 12" ALIANTE subwoofer:
Does anybody know an AMP who would do this better?

An externally hosted image should be here but it was not working when we last tested it.

I think the guy has three phase linears for sale, that is why the ad is confusing.
Better...lol I wanted to know what was better and now I don't really know what to think.

@Jol50,
I have nothing to sell!
My installation is 6 years old and I will not change it.
The Aliante 12" subwoofers have a very poor grade of efficiency.
I tried a number of AMPs (f.e. DLS A1, Autotek Mean Machine, ..) to drive this subwoofer.
The only AMP that pleased my ears, that can play loud, is quick, melodic, ... is the Studio 500.

Oops I mean the ad I posted before that guy is selling amps. The Zapco certainly are high quality amps, if it works that well don't move it!
-What is the rms rating of the subwoofer?
-What is the sensitivity rating of the subwoofer?
-What is the resonant frequency of the subwoofer?
-What is the resistance of each voice coil?
-How many voice coils?
-What volume/size and type/design of box?
Zapcos amps in general are very clean and well built, as long as that amp is rated to produce a little more than that subwoofer is rated to handle and as long as you are running it bridged into a single 4 ohm load it should do the job.
