Nickel membrane small diaphragm capsule, similar design and sound to the Neumann KM54 capsule
very good condition, working perfectly, sounds great!
capsule only, you will need an MV690, MV691 or MV692 to use this - it will also work with the tube M582
New membrane by master Gefell tech Siegfried Thiersch, seal on capsule intact.
Light cosmetic wear, see photos.
