FS: Pair Audio-Technica AT837 gooseneck mics

[KBnewbie]

Hi,
Got a pair of Audio-Technica AT837 gooseneck microphones.

Please note that these are without the phantom powering/balancing module.
They date from the 80's and are early Unipoint types.
The are discontinued and the only specs I could find are:
Small diaphragm cardioid condenser
Freq 40-18K no +/- dB noted
Sensitivity -45.5 dBm
They are semi rigid type gooseneck meaning they stay where you point them.
They have a screw mount base with washer and nut and are 370mm in length.
The stem and head surface is a little tarnished.
The purchaser would need to sort out the power supply required to power them and balancing transformer if balanced operation required.
Many years ago I did use them powered from a 9 volt Battery with resistors and cap however dont recall the exact schematic I used and I used them unbalanced and they sounded quite OK.
They each have 2 x red wires and 2 x yellow wires and overall screen.
Offered at $50 for the pair including postage within Australia.
