... the solid-state Ongaku?
Just kidding (about the Kondo's original masterpiece...) but I've been VERY, mean V-E-R-Y, impressed by this German-made DIY amp, a 20 W Class A amp which used a kit from L'Audiophile...
Compact sized, superbly built and sounding... a beauty!
I deeply thanks the anonymous builder of "this"...
