This is a beautiful piece from a non-smoking home….The wood case is super nice and over built….I upgraded the lamps to LEDs from Mac, new differential pair transistors (gain matched) from OnSemi, new driver transistors and new output transistors (also OnSemi and matched)…The outputs are sitting on silicone wafers for better heat transfer…Cleaned/lubed the controls properly, biased, etc…The chassis is beautiful and I even rebuilt the faceplate using new sealing foam…Less than 15mv of DC offset per channel and sounds FANTASTIC!…..Free Shipping!!!!
