RCA 77DX Computer Modeling

Creating a complete SolidWorks package describing an entire RCA 77DX ribbon microphone was quite a project.

Here is the cover shot, in case it got by you the first time it was posted, nearly a year ago. It is missing the circumferential band with the RCA logo, but has the recess like the early 77D and 77DX mics that was designed to accept an engraved brass ring. This was probably a very difficult part to produce. Later on the recess was made shallower and a simple "foil" sticker was used instead.
