Restored RCA BK-5A

The RCA BK-5A ribbon mike is back in my hands.  Here is a before picture, followed by some after pics.  The mike was sanded and repainted to the original colour.  The ribbon was completely missing inside the mike (which is what I suspected - I couldn't find one when I took it apart), so Clarence cut a new one and installed it according to the original RCA specification (size, tension, etc.).  He put on a new cable since the old one was cracking up.  The little screws were mostly missing, and the ones that were there were stripped, so they were all replaced.  I didn't have the original shock mount, so Clarence supplied a reproduction shock mount that looks like the original.  This mount was pretty expensive, but what are you gonna do.  He supplied the knurled knobs for the mount, but unfortunately the threads on the mike are kind of screwed up - somebody must have cranked on the wrong size thread.  So I'm not sure how to fix that. I had the little RCA medallion and so that is glued back on.  It looks pretty good, and now it's time to check how it sounds.

RCA BK-5A

A quick update ... my RCA BK-5A ribbon mike has been restored by Enak Microphone Repair, and is on its way back to me! It should arrive within a few days along with a repaired mount for my old Sony C37-FET condenser mike.  I can't wait to try it out on a vuvuzela.  Actually, the only reason I said vuvuzela is to see if I get more google hits.  Vuvuzela ya later.
