Build a really good 3A current source in the speaker stage?

Progg70 · 9th November 2005, 08:08 PM

If you would build a really good current source that have a high current, 3A in the speaker drive stage. See the picture; how could it look like.
I have searched.

Depends on what you mean by really good. You can build a
decent CCS with an N channel Mosfet and a generic npn
transistor.

Reality TV? Documentary? Nelson visits Disneyland with the grandkids? Star in a movie with Bruce Willis? Sanda Bullock?

Inquiring minds want to know more
