recently a nice pair of unknown vintage microphones came into my hands.
These were probably the first (sorry Mr Fouxman...) hybride ribbon/condenser mics ever made.
An omni condenser capsule is sitting underneath a ribbon motor. You can switch between omni, cardioid and fig-8.
They have a Raytheon 5703 tube inside and two trannies, BV51 and BV56. More pics of parts can be made.
Unfortunately i do not have a PSU...
Please have a look at the pictures. Does anyone have any idea about who was the manufacturer of these?
They only say 'JB 8CS'??
Thanks for your interest!
