Right on. I've been reading this stuff too. And it seems you took everything out that you could replace. What did you replace C1, C2, C3 & C4 with?
C1 WIMA FKP2 - .01uF /63v (Polyester film)
C2 WIMA FKP2 - .01uF /63v (Polyester film)
I chose those capacitors because Marik had recommended that value for those, and they fit well.
C3 WIMA MKS2 - .47uF /63v (Polyester film)
C4 WIMA MKS2 - .47uF /63v (Polyester film)
Because that's what was available and they fit. I may try different values, if I can find bigger ones that fit.
C11 Panasonic - .033uF/ 100v (Metal film)
C12 Panasonic - .033uF/ 100v (Metal film)
I chose those, because I already had them and again, they physically fit.
It also looks like you changed the values of D4 & D5?
I didn't change those.
And did you just cahnge them out from ceramic to metal film or did you change values too IE: C12.
The resistors I used are good metal films. When I was first testing the mics, I noticed pretty wide tolerances for some of the stock resistors. So, I decided to replace most of them. Then I hand matched everyone, so that the values were (nearly) identical in each mic. I hoped that would make the mics exactly the same in every respect, but that didn't work, since one mic has more gain than the other now.
