Hello I'm so happy that I became the vedor of audiokamar since today.

I'd like to introudce our most welcomed free JLH-2005 free PCB to all DIYers. JLH amplifier is a classic class A amplifier introuced since 1960. There're 2 version follows: JLH1996 and JLH2005. This free PCB is the latest version. You can find the design here:

The circuit is pretty simple, quite easy to build even for newbies. Now the PCB is the second version, a few bugs on the first version were fixed. No special components required.

This free pcb was introduce on diyaudio forum since 2 weeks before, more than 200 has been deliveryed since then. We'll keep on making and modifying the design with your feedbacks. Hope you can have DIY fun with it.
