Hey,
I think this is Matador's list of things he tweaks in the standard c12 build.
I have ordered the CM transformer ordered, as I think Cat5 has that in his and I thought his c12 sounded great.
Are people aware of other tweaks ? I have the Campbell cap installed.
Thx !
c12 mod:
From top-to-bottom:
1) Chunger's 34mm edge-terminated capsule
2) NOS RCA 12AT7 (screened from my stash for lowest noise)
3) Silver Mica caps for on-board filters (C10, C11)
4) High impedance 30M and 250M resistances changed to 100M metal film
5) Very nice NP0/C0G ceramic cap for 1000pF C13 gate coupling cap (my favorite all-time audio coupling cap in 1nF or less sizes)
6) Cinemag CM-13114 12:1 output transformer
I will also go through and do my normal "re-tap every single hole for a stainless steel 2-56 1/4" machine screw" mod, which I have found makes a profound difference to the physical feel of the microphone (it feels tighter, and more "solid", if that makes sense). Or it might just be my imagination, but I tend to strip the stock 2mm screws out fairly frequently.
