Philips EL6030 Dynamic
Here is a wonderful looking, space-age, large diaphragm dynamic microphone made by Philips.
The microphone actually has three different impedances available from the output transformer. The 500 ohm output has been wired to an XLR socket, so no special cable is needed.
The diaphragm is huge and made of stiff aluminium. Consequently the microphone is rather lo-fi and ‘vintage’ sounding.
Would make a great prop or effects microphone.
