you want the 6072a

Id whip out the tranny and stick in a Cinemag (not sure which model number off the top of my head sorry) I did a mod of the Apex 205 a couple of months back and it sounds AMAZING!! (tbone rb500 here in the uk). Firstly I retentioned the ribbon correctly, replaced all the internal wiring with solid silver jewellers wire, replaced the transformer with the cinemag, took out windshields and extra layer of mesh, ground of the ****ty aluminium finish to reveal the lovely natural brass underneath, took off the ****ty blue paint to get the lovely gun metal finish, enameled it, interally padded the lower half of the body with very very dense felt (to remove a mechanical resonance, worked a treat!) and you would never, ever know this was a Chinese mic, it sounds nothing short of stellar and looks smooooth too. I'm going to do another couple, but this time i'm going to try and solder with silver (with the help of a jeweller friend), or do some silver fusion (were working this one out) instead of standard solder. I can't wait!!

Dang. Best Step-By-Step ever.

...ditto!

...and the guys behind this build (Matador & Chunger) are great guys as well...very talented and helpful!...the DIY crew has really nailed some of these clone builds, and taken these projects to a higher level...now, if only my soldering skills were up to the task...

Can anyone please tell me the correct way to install the (AA) BV11 transformer for the Advanced Audio Mod?
I wasn't thinking straight and cut all the wires to my 7-pin jack without taking notes/pictures. Starting from a clean 7-pin jack, what wires go to where? Which wires need to be soldered together?
