Newbie could use some help

[kazanoom]

I installed a new capsule in an Avantone cv12 and now the gain is very low. My soldering skills are lacking for sure but I know I connected all the leads to the right places. Thought it might be the new capsule so I went back to the stock capsule  and it's doing the same thing. No noise or distortion just very low gain. What do you think went wrong?

Clean all new connections thoroughly with isopropyl alcohol carefullly! Any flux or oils from your hands will cause problems in any high impedance circuit. Pictures always helpful.

Solved, Apparently blew a tube in my preamp and the mic wasn't the problem, thanks.
