    You've got a sharp eye for sure todd!!! I went with a jp33 instead of a salt,something about those boards that I m confident in putting a lot of power through, thanks for another killer vid

    Great video Todd that's so the temperature is something every repair guy should check for I have a video am going to upload soon with a issue I have with a sundown SFB 1000D

      Checking temperatures is a huge step in my business. I like to monitor temperatures for about 2 hours to make sure there is no thermal runaway or specific heat issues.

      Yes, this was an amazing find in my opinion for both Sundown and the owner.

    I purchased a salt 4 from the yard sale on their website. When it came in the mail, I powered it up on the bench made sure it worked because you have to report any problems within three days. Needless to say I installed it two weeks later and when it powered up and started to output, it started smoking send down won’t do anything about it. I opened it up and several transistors. Let the magic smoke out. I don’t know why.

      Did it start on the bench? If so and it had no issues, then your input voltage is what you will need to look into. Also, make sure your impedance is not too low. This is an all-too-common scenario.

      Baffles me how this made it through, obviously, they do not do full load testing as they would have seen a substantial reduction of output power. Thank you for the channel support!

      As of the first of the year I no longer service Sundown amplifiers except for a few select versions they had in the past. This is one of their latest designs (who knows what all is defaced) so I do not know what an average repair cost would be. I can say that if you have anyone tell you it is more than $150 to repair they are overcharging you.

    Nice find. Would you attribute the output section failure to this non active inductor?
    I've had more than my fair share of sundown equipment, some actually really good experiences (old OG stuff) and some bad ones too(newer gear). The more recent the gear, the less reliable from my experience. Its been a while though for sure. Maybe it's better, but this video definitely doesn't inspire confidence or trust again.
    I don't buy sundown anymore, haven't for some time, and have switched to other more expensive and value brands too. They all give you the same shit quality, but are at least are more reasonable with excessive profit margins.
    Makes me wonder how many other salt amps or other have QC issues like this, and we're denied warranty. There's definitely other quality control issues, like protection circuits that don't work. The amp just goes up in smoke. I've personally experienced it, and saw it first hand with bass buddies. I couldn't count how many times I've protected the old shit, never repaired, never a problem. They come back online and just work. They don't make them like they used to.. You pay a premium for quality, and pay even more so for the name as well, and this is what ya get.
    I haven't bought anything from them since the zv4 days(6 years ago?) and I won't again... I know I've saved a bunch.
    Awesome videos lately, you get a thumbs up from me every time. Need to comment more for the algorithm for sure, you deserve it.

    • @ellensburgamplifier
      @ellensburgamplifier  2 года назад +1

      I truly thank you for your comments. Here is what I would take from this board. There is a thermistor on each side of the output board. When one side is cooler than the other from a missing inductor (which leads to no load on the transistors), the thermal protection circuit may not "trip" as designed depending on if the thermistors are in parallel or in series. This out-of-circuit inductor more than likely may have contributed to the other side's complete failure in my opinion.

    Hi Todd
    It was a very good point. Thank you for sharing this experience
    I am very interested to learn this type of class D amplifier. Is there a video on your channel that explains how this type of amplifier works?
    I am slowly watching and still haven't been able to watch all the videos.
    I sent you a schematic in the email.
    thank you

    • @ellensburgamplifier
      @ellensburgamplifier  2 года назад

      I always recommend learning how a class AB amplifier works before getting to know class D. Even though they are two different styles of amplification class AB tends to be the hardest for people to understand.

    is this a full bridge design?

    • @ellensburgamplifier
      @ellensburgamplifier  Год назад

      This word is widely misused in relation to the topology of an amplifier. ruclips.net/video/b6tyjXSHvGg/видео.html Sam covered it well. The negative output of a Salt 12 is bonded to secondary common "ground" and full-bridge amplifiers are not like this like the Taramps where you will see both speaker terminals with positive voltage.
