Have you considered a timing relay unit/switch sequencer so that the amp is the last thing that turns on and the first thing than turns off? These can be programed to turn on and off in whatever order and delay you choose and are fairly inexpensive. As far as speaker wires touching where they shouldn't you just have to be careful and trim them accordingly.
Recommendation Repair Technician
Can anyone recommend someone who might take on an amplifier upgrade request? Here is the situation.
I have a class d amplifier that I want to keep and use for a very very long time. The original company is closed
The design is so prone to blowing Gen-Fets that most people keep them in the closet collecting dust. The reviews consistently put this class d design as having the greatest soundstage.
It uses an open ground. If the source is not turned on before the amp is then the Gen-Fets blow. This means that the source must use a UPS in our rural power area. If any stray piece of speaker wire touches the close proximity other speaker post or the case the Gen-Fets blow. The fets are becoming harder to source. These are like a Lamborghini built on carbon fiber. Any bump can damage the carbon fiber (metaphor only).
This is not my profession but to further just describe the situation, is a fix possibly to change to a push pull power supply, add a start capacitor or change design to chassis ground?
Anyway, smart people can suggest smart ideas BUT do you know any smart people who also use the soldering gun?
I appreciate you.

@geworthomd that’s some amp you got there. Sounds like a winner. If I were you I’d start a thread asking for recommendations on something with similar sonics and better design and reliability. |
Thank you dekay. I will call them. |
