Tesla AMD 410N Cardioid Dynamic
Here we have a pair of Tesla AMD 410N cardioid dynamic microphones in good working order and nice cosmetic condition.
The Tesla company made dynamic microphones in Soviet era Czechoslovakia. Tesla had manufacturing links to AKG and Philips for their microphone expertise.
Standard DIN output sockets. £85 each or £149 for the pair.
