Soundstream VGA 600.2 please help !
 
I have a Van Gogh 600.2 with some burnt resistors and diodes.
I have not been able to get the schematics. Not on the forums, contacted Soundstream but they only give them to authorized dealers, contacted the importer in my country and he tried getting it but was not succesful.

Would anyone happen to have the exact same amp ? Maybe on his he could see the values of resistors and what kind of diodes they are.

Here are some pics:

I have the 1600.2 of this amp, I can look in the morning.

I have the 800.5 schematics and have seen pics of a 500.4, but the circuitry seems different.
Who knows, the 2 channel 1600.2 may be more alike.

How does this look, like the same?
R20, 25, 27, 30 are 5.5K 5%
R24, 28 are 550ohm 5%
D53, 54 are 1n4756A

I get no audio out of mine, this area on my board was hot at one point. I have no schematic and soundstream won't issue it.

Good luck,
Cory

Hi Cory, thanks for the pic and information.
I'll have a look with my father.
Not being able to get the schematics sucks.

That's helpful, thanks.
Aren't those 560 and 5.6K resistors ?

We are still having problems with this amplifier.
We replaced R20,24,25,27,28,30 and the four resistors on the left under the mini-PCB, which was unnecessary but well...
We also replaced Q34,35,36,37 and DZ53 and 54.

Very quickly after powering on the amplifier some of these components get very hot so we power off the amplifier. We still don't have the schematics for this amp.
Following the traces this section seems to be linked to the 4 indicator LEDs. These components should not get this hot, so something must be wrong somewhere.

Also, the indicator light of the RAIL+ voltage is lit while the RAIL- voltage LED is not lit (or vice versa, can't remember for sure, which is not right. The LED functions as it blinks at power-on.

Anyone have a clue ? Hard to tell without schematics.

I haven't looked at mine in awhile, but my -rail led is bad and wont light.
I can get audio out if I change a switch setting for the rca's. I don't recall the name of it.

Need a soundstream salesman to get the schematic! :mad:

azvrt 14th May 2012 12:48 PM

I think you are referring to the 'RCA SENSE' switch.

I contacted Soundstream USA they told me they only forward the schematics to authorized dealers. Since my local car audio shop stopped being a SS dealer I contacted the importer for my country (Netherlands), he said he would try to get it but he later said he wasn't succesful...

Azvrt I'm curious if you ever ended up getting any detailed pics? I also have a 1600.2 and 320.4 both in the Van Gogh series but damaged and missing resistors and mosfets. I'm really hoping maybe Brandes.cm might be able to email me some clear pics of the inside of his 1600.2 Dang, I would even be willing to maybe send him some $ through PayPal if the pics are detailed enough, hey it'll save me having to send it out anyways right.
