Studio Monitor Bi-Amp PCB
This is a single sided design
you will have to provide +\ - rails with good filter caps It uses the LM3886 http://www.national.com/ds/LM/LM3886.pdf or the or the LM2876 http://www.national.com/ds/LM/LM2876.pdf In my application I found 40 watts worked great for the horn with 68 kicking full range ! Attached is a PDF that you can use to make the PCB it is scale mirrored just print it on glossy color photo paper and then IRON the toner on to fresh clean copper for an etch resist ! It really works radio shack has the Ferric Chloride for etching: It's like 16 ounces for 9 bucks ! |
