Hi guys,
I've done the apex 460 to ela m (style) mods pretty much exactly as is described here:
http://www.allthisnoise.com/All_This_Noise/Apex_mod.html
After I swapped in a Tim Campbell CT12 and changed the PSU zeners to get 114v I found the mic became very "full" or tubby.
I have checked the relevant schematics and it looks to me like I've wired the capsule correctly - I have the backplates wired together and wired to the junction of c4 and r10. I have one capsule side going to the junction c5 and r9 and the other side going to the circuit ground that meets r7. What is strange is that if I short the c5/r9/capsule junction point to the mic body it behaves properly - it loses the tubbiness and opens up to become very clear. I guess I could just wire that in permanently but I'm worried I've done something wrong somewhere and even when I do that its still not as bright as I imagined it should be. It's very natural and very nice sounding but seems to have less pronounced highs then my mk47 with a beezneez K7. I actually miswired the capsule initially, treating the two backplates as if they were the capsules and one of the capsules as the backplate so I'm hoping that didn't damage the capsule.
Anyone had a similar issue or might suggest where to start troubleshooting?
