Vintage Original Telefunken M221B german tube microphone. SN: 2818. This is great microhpone for recording acoustic instruments: very warm and rich sound. It makes any modern Telefunken/Schoeps lifeless if compared mics side by side. It comes with the most desirable vintage Telefunken M934 capsule. The microphone has been completely and professionally serviced by AEG microphone company in Moscow: installed NOS Telefunken AC701 Tube and vintage AKG U28 output transformer. Also AEG has replaced microphone shell on vintage AEG microphone shell made point to point (only because original mic shell had a lot of dents and scratches). Comes with AEG PSU (110/220) and original vintage Telefunken Cable.
