All about the tools and techniques involved in capturing sound, in the studio or on location.

Ah yes, the STC4033 -- essentially a British version of the American Altec 639 (or was I the other way around? ;) ) Yes, it was a popular mic on studio booms for the early years of TV.

No idea why you could see arcing, though. The ribbon was isolated from the connector via a transformer, so phantom power shouldn't have reached it!

I don’t know Hugh and it’s only a guess about the mic’ but I think I’m right, there again I left in 1991 so it’s a distant memory.
