Hello! I'm trying to find out information about a microphone in my posession, and it's been elusive. It's a small diaphragm condenser with a silver housing made by Philips. The model number is LBB 9080/55 Nr948. It was apparently part of a matched set at one point, as there is also a dual power supply LBB 9071/50. It was made in Austria. I can find no information about it; the sound is very unusual for a small mic like this. A lot of warm bass emphasis. Has anybody ever heard of this one? I think it's probably at least 20 years old.

Thanks for any help...

Doug
