Thank you for the top tip on the pots, I think that's where I went wrong on one of my 1507 but I had it on a very low current limited supply so no damage done. Keep up the great work on the videos. Thank you for sharing your knowledge.

Excellent, you know very well how an amplifier works. I have the same Hakko 808 desoldering gun. I been fixing High End audio for many years, I am in electronics for more than 42 years and I can tell you, are a Master. Hope un that days start making vídeos of my works. I work fixing many Audio Research equipment. Thanks for share. Cheers .

You can separate the audio section from the power supply by removing the bridge rectifier section (right after the secondary windings, you'll find the dual diode rectifiers). They are usually right next to the mosfets of the power supply, on this amp you can see them screwed directly to the sink next to the mosfets that are clamped down.

great intro. worth a second look at these hayday alpine amps after viewing this video. own a alpine eq with the BBE function (reason why searched out). though dont know how going to integrate this old four channel (front and back left and right) into a modern pioneer h.u. gotta lot of other great youtubes to watch. wish to finish another time due to how interesting understanding amp guts are when purchasing and comparing new amps.

Thanks for doing these videos, I really appreciate seeing them. Would you prefer using this amp as a full-range amp for components, or as a subwoofer amp? Components are Boston Acoustics 6.53 pro or 6.5 pro which are 3 ohm nominal (depending on what fits). Thanks again.

Grat video im learning a lot from you keep them video's coming! I have a question if an amplifier has 8 output Mosfets and it has 2 extra empty spots for 2 more that was not installed from factory what will happen if I install them would the amplifier perform better ??

How do the toroids work on an amp do they step the voltage all the up to rail voltage from 12v ac am guessing the fets alternate the the 12v dc and one side it stepped up through the toroidal transfomers to rail voltage plus and minus maybe plus one side minus on the other? am I close? or does each side do plus and minus to each side of the amplifier stage.

I see you're using the Sigelei 213 with a Kanger Subtank mini (with the RBA?). I vape as well. It's been about 4 years since i quit analogs. For me, vaping has turned into more than a life saving decision. It has also been a great avenue of incorporating my electronics knowledge into my own self-built mods and improving upon retail devices. Since i'm into board level repair, as well, i enjoy building mods for myself and friends. Do you ever tinker with building mods or vaping boards.........Evolv DNA.........Yihi? Or is vaping just a way to quit smoking for you and that's it? I'm sure you already know this but i wouldn't vape around all that test equipment. I've already had to take apart my laptop and give the logic board a 99% iso alcohol bath. It wouldn't turn on one day because it had a nasty film of VG/PG from vaping, over the board components (me being a dummy and blowing my vape right at the laptop while using it). Great repair BTW!

I've had it for years and the label is worn off. I wish i could tell you. Its nothing special. I'm pretty sure it's a 60/40 rosin core based solder.

So where do i need to ship my soundstream reference 700sx to for u to repair it sir?
@The_Active_Region6 жыл бұрын
In my previous video I explain that I cannot take on repairs that I cannot get service manual schematics for. It cost a lot of money for you to ship back and fourth and is also costly for me in time I waste if I can't figure out parts that may be burnt beyond recognition or if there is a fault that is not easy to find without the service information. One can spend hours or even days on fixing an amp without any service information. I don't have that kind of time to be guessing for hours or days ya know? Sometimes its easy but you don't know till it's in front of you and deeply into it. Sorry

+Internationalf250 could be fine and the ledriver chip may ne bad.. unlikely but possible. Also check the +-15 volt supply in the amp sectio
@Internationalf2506 жыл бұрын
Kev31779 I have +- 15v and at the led board connector I have ground on the gray wire and a couple of pins at 8v so all of the led's are blown or am I missing something? Thank you for the reply and for teaching me so much about electronics.
@The_Active_Region6 жыл бұрын
Does the amp work other than the led's?
@The_Active_Region6 жыл бұрын
Could be a bad ground, that amp cooks ground traces on the back side of the board near the power input. Also check that there is continuity between pin 1 of led ribbon cable and the power supply gnd. Other than that you will need to start probing ic's like ic702 and ic703. Also the surrounding transistors. Ic 702 is problematic but not likely to cause all the leds not to work but not impossible.
@Internationalf2506 жыл бұрын
Kev31779 the amp works fine and all of the traces look good. The ribbon cable tests fine but if I connect 8.1v to the back of either + tab for the led and ground the center pin on any of the 3 bulbs nothing happens. Does that mean they are dead?
