Inductor help

[Salas]

Not really good for vibrations. If the amp works well in the end, redo them and put enough elastic glue so it holds well.

I already siliconed the thing to the board very well(after the pics were taken) so vibrations are not an issue any more i also did all the caps and other inductors. Hopefully this thing powers up when I get my new mosfets.

It doesn't look like it's wound correctly. Maybe someone like Eva will correct me if I'm wrong but...

Viewing the inductor from the side of the power supply FETs, the left winding on the original passed under the core just before it went into the board. The right winding passed over the top as you have it.

I believe it's going to make a big difference. At best, it won't do it's job properly. At worst, it will cause the supply to fail.

The attached image is an original inductor.

That is not from this amp. I own two and both have windings of 5 wires each it appears those are 3?

 

[Perry Babin]

It's not the number of strands that are the problem. The windings don't appear to be laid down the same way.

If your left-hand winding passes under the core just before it goes into the board like the one in the photo, then there's likely no problem.

This photo shows an inductor more like yours.

Hey I got the new power supply in and this amp works 100%. the coil inductor that I made is clearly doing its job and im very impressed. Im 17 years old and was able to diagnose and fix this amp with the help of a few people. FYI this is the 3rd amp I fixed this being the most complex.
