Troubleshooting MOSFETS

Mike L. · 9th February 2004, 02:55 PM

Hi,

I just finished assembling a Zen amp. When I power it up, no sound is coming out. I would like to verify that I didn't accidently zap the HEXFETs. Is there a simple check I can make with a multimeter?

Thanks.

Hugo,

Thanks very much for the link. A most helpful site. The mosfets were o.k.. The problem was I had them in backwards. I am going to fully explain the problem in another post.
