Circa 1995 "Soundstorm" ... Soundstream Knockoff... ala "Rockwood" and Rockford...

Go to throw it in a dude's car... why? cuz he had it and wanted it in there... I don't ask questions anymore -- I just do what people ask... it's less of a headache.

Well it was just cooked.. it wouldn't turn on, protection light lit up like a christmas tree... no sound output... and the right side of hte amp was just BAKING

Rip it out - take it home... burnt this, burnt that... messy messy...

Circuit layout looks like something that was thrown together at the last minute, no less.

So I start yanking fets, and sure enough.... i find the problem buggers... threw it back togeter with channels 3 and 4 removed -- works -- International Rectifier has Fets in the mail... and this piece of junk will be working by mid-week.

God I'm good.

    well that was my opinion too.. its 175 x 2 bridged (4 channel)... barely enough to make pioneer 150 watt subs move.

    I told him he could get a DEI / Viper 250D (250 x 1 @ 2 ohms mono) for 39 bucks from Ikesound refurbished with 90 day warranty -- he was like "that's expensive" --- for a 300 dollar amp.. um.. ok... so i end up rebuild this - go figure... i'm too nice!

    Gotta love those "knock off" brands...

    Kinda like the White Van Scam speakers..

    Paradyme (spin off of Paradigm)

    Acoustic (spin off of Acoustic Research)

    Ephiphany (just meant to sound high end...)

    Dymaudio (spin off of Dynaudio)

    Dogg Digital (apparently to cater to the Hip Hop Generation?)

    *scratches head* this blows my fricking mind.

    Parts come in -- replace outputs for channels 3 and 4... plug the sucker in... it works.

    Let it play for 10 or 15 minutes... go smoke a cigarette... come back... still workin ...

    So I say "well lemme hook channels 1 and 2 back up to make sure they're still working - just cuz i'm paranoid" --- so I do that... and it still works fine.

    So at this point I'm like ready to give it back to the dude.

    But I'm like "Hmm... I didn't actually run 1, 2, 3, and 4 all at the same time... I better do that..."

    So I run all 4 channels into 4 ohm speakers.

    Turn it on.

    POOF - magic smoke.

    Not just smoke... but what looked like fireworks. Bad ugly ones.

    Fizzle Fizzle Salt and Sizzle...

    I'm done working on junk.

    I've got a 90% success rate on name brand decent stuff.
    (MTX [x 6], USAmps, JBL [x 2]... then there's that f****** RF that cody sent me but I couldn't get it going).

    I have no luck with junk -- and I think it'll only get worse.
    (Jensen, Urban Audio, and now Soundstorm -- only one that worked out was the Optimus).

    I really don't get it, in theory, if you figure out whats wrong, put the same parts or acceptable replacements back in... it SHOULD work. I was made semi-sick though when the traces started to burn off the board while I was soldering. I've never seen anything like this, but it looks like the traces are almost "taped" onto the board. It doesn't look etched at all. Weird... Really weird. What a friggin mess.

    It didn't even have a plate holding the transistors to the heatsink. Some companies will basically "weld" the backs of the transistors down ... others will simply use a big honkin steel bar that bolts to the heatsink and sandwiches the transistors against it. This piece of **** used "zippy clamps". They look like these...

    binderclips.jpg

    ... but without the silver handles.

    I was like "WHAT THE **** IS THIS !?!?!?!?!" junk junk junk junk junk. As the metal heats up, they become less "tight" -- damn things loosen up and you get crappy cooling.

    Anywho - I drilled the **** out and put real retainer bars on there. And for what - I waste my f'in time. I've got about 4 hours in that son of a ****. Fer what... nothin. And the dude's gonna be pissed that I couldn't fix it - and you know what I'm gonna say... "Dude, it's a crapshoot... ya didn't loose nothin... go spend 39 bucks on the Viper amp... if you have a problem witht hat, shove it up your rear"

    You gotta be kidding me.. They CLAMPED the FET's to the heat spreader
    bars? They probably didn't even put any thermal compound on them either?

    nopers - no thermal grease, but they had the nice little pieces of nylon material (insulator) to keep them from grounding out, but guess what... it wasn't even nylon or any form of decent looking plastic... looked like paper with a film over it. it wasn't what i expected to see at all inside of an amplifier. normally you'll have a nylon or something similar, thin obviously so that it has good heat transfer properties, but not so flimsy that you think it'll melt itself... and a slathering of thermal grease between the bar and the nylon... then between the nyulon and the transistor... this thing... metal... paper... metal... clamp. how wonderful.

    considering a tube of grease costs about 2 bucks, they're saving 2 bucks an amp.

    Boy...that takes the cake for electronics assembly shortcutting...but as they say...ya get what ya pay for. I can't believe he's balking at a $40 monoblock with a warranty...

    I bet if I dug out my old 1990 RF Punch 45 it would light up and sing...now there's a solid-as-a-brick piece...still in very good physical condition.
