mA726

Here is my version of drop-in replacement for uA726 part used in Buchla Easel. I have tested this before here. I ordered the first proto-batch from Eurocircuits. Because of two SMD-parts it's very compact (width = 37mm and height = 17mm). For LM3046 replacement I use ALFA-parts AS3046 (Vbe is matched five times better for the NPN pair than in the original with +- 1mV).
