Great advice. Thank you.Okay, if they are functional, then build the EBs. That way you have 4 good mics. You could find, through swapping capsules, that the ULS body makes a big difference, and that you prefer the ULS capsule in the DIY EB, and the CT12s in the ULS bodies. That's a lot of effort though; and it's effort that can be done late. Build the EBs with the CT12s, then swap capsules if you feel confident.
Have you built a mic before? If not, it could be worth finding the cheapest capsule with isolated backplates available. Build both EBs but don't ins tall a capsule in one, then install the cheap capsule in the other. Once you have a functioning mic with no Hi-z rustling wind noise, then install the two CT12s.
No, I've never built a mic before. But I have opened up and repaired an AKG C12 VR that someone wrecked at a studio I sometimes work at. Someone opened it up to change the tube, and ripped out most of the wiring that was going to the tube socket!! I found the schematic on line, found the exact color coded wire I needed from an old AKG C12 mic cable I found on the floor of the studio's basement, busted out the soldering iron and went to work! These mics aren't cheap. . . So I was a little nervous. Ya think? The mic was successfully put back into service.
While I don't think of myself as the "sharpest tool in the shed", I try to be that guy who is smart enough to know when he's not smart enough to go any further! If you've read my "414 Dilemma" post above, you'll see that practice put into action when I decided that I wasn't smart enough to proceed any further with my attempt to change the capsule on my 414 B-ULS. That's why that microphone still works and makes me money today!
I will definitely follow your advice about using a cheap capsule when I fire up these mics for the first time. Thank you Delta Sigma.
Getting back to that C12 VR, I couldn't believe how the wires to that nylon capsule were terminated. Cheap little clips that were almost falling off. WOW. . .
