Hi all This is A Re-post I wasn't able to find the answer. so maybe a fresh set of Eyes.
I'm working on the Aurcyle FET U87 mic upgrade posted.
my question if some one has done the upgrade. I was going to experiment and figure it out. But thought it would be easier to ask. My thought was to use all of the better components and use for D2 2A1015 and the 2n3819 for D1 and use the stock 1/4 w 3.9K for R6 or the 2.1k resistor and not use the 5k pot. So it would be none adjustable. If that makes sense to do it that way. Does any one have any thoughts on this.
