For Sale a pair of Cardioid Electret Condenser Microphones - Tested for proper function. Each includes: Removable Windscreen, Table Stand, Mic Clip, 5/8-27 Stand Adapter, red rubber Battery Cover for end of AA battery, Instruction Manual, and Vinyl Case with Cover. I purchased these mics for my dad to use with a stereo cassette recorder, and could be used with any recorder having 1/4" mic inputs. I suspect they were used only once or twice in the early 1970s, and were always stored with no batteries installed, no use for 50 years! - no battery leakage, see photo. Great Stereo when used as a pair shown in pictures (NOS placement)! Please email me via eBay if you have any questions. Will only sell as a pair.
