There was a package in the mail, sent from a car repair shop somewhere in Germany. It contained the usual things: Paper flakes and microphones. But what kind of microphones were these? 2 gooseneck mics from Philips, named Philips LBB 9007/06 – obviously the same as the Philips EL6025 gooseneck mic – and the slightly different handheld version with a missing connector, and wires sticking out of the housing instead (it later turned out that this microphone, before we ruined and frankenmic’d it, had been the Philips LBB 9005, which supposedly adheres to HiFi standards). They definitely looked like they had been living in some sort of tourist bus before.
Fitting an XLR-socket into the broken handheld version was out of the question, so I took a 3-pin-cable, soldered it onto the loose wires and wrapped a knot out of isolation tape around the cable, until it couldn’t fall out of the housing anymore. Now for the test (of the handheld version): Oh, amazing. I talked into it and it picked up my voice. After the initial euphoria about reviving an old microphone was gone, disappointment set in. Its sound was really nasal and thin, almost like it was broken. I compared it to the gooseneck microphones, which looked like the same capsule was inside, and the difference was really obvious. There was something wrong with this.
On further investigation it turned out that the handheld version had a capsule that didn’t have a plastic diaphragm – instead it was made out of some kind of ALUMINIUM FOIL! That was not expected, and as the saying goes “curiosity killed the cat”, we managed to break the capsule in the progress. And forgot to take a picture of the aluminium foil diaphragm.
So it was time to check out the gooseneck version: The sound was thin, a bit boxy, not unpleasant, but kind of unstable sounding in proximity. Shouting into it leads to an authentic broadcasting announcement kind of sound. Not very usable for studio vocal purposes, but maybe as an instrument mic? One day it ended up in front of a bass amp, It did quite ok, but I guess there are better alternatives. Still, the usability on different instruments is still to be found out by brave explorers to this day. At least they have really stable goosenecks. And we have two of them, to they might just end up as dynamic drum underhead mics some day. Yup, underheads. That’s what they deserve.
