Hertz HP1D problems

[Perry Babin]

It's only a suggestion. If someone has a transistor that has worked properly in the amp you have, use it.

Hi guys, I'm back. I studied and learned a lot about class D. Now, I want to buy FDA24N40F (yes, it's a good suggestion, thanks Perry) but I have some questions:

- higher Rds cause more heat---> can be a problem? Heatsink is able to dissipate all the heat or I must install a fan?

- about over current protection: this circuit doesn't use Rds as current sensing resistore, I'm right?

- where I can buy the clips on the photo? (I'm ordering from mouser, but I can't find them)

Please don't post in a repair thread that was started by someone else unless you are trying to help them.

Start a new thread.

I see the burned area now. I'll email you if I can find something helpful.
