WOW!

That's a beautiful amp you've made!

How does it sound?

What output transistors did you decide on using?

Well done!

Really nice work. One of the nicer amps I've seen put together by a DIYer. The only issue is that the caps are enclosed and the temp rise won't help their longevity if that's any issue at all.

Does anyone know if Dr. Leach is still selling the PCBs for his amp?
