RCA 77DX PAIR MIKROPHON RIBBON ULTRA RARE

These two microphones have passed a selection among fifty identical competitors, in practice they are practically perfect, like new (maybe I have one, never used, unsold warehouse stock) .. they are part of a set that a well-known national broadcaster used for filming classical music on location ... (La Scala Theatre in Milan) .. telling you and comparing them how they sounded is impossible, you wouldn't believe me .... it's like listening to a U47Tube ... I would never have sold them if it weren't for my now advanced age, so the price justifies the reason I put them up for sale, complete with their original case from the time (manna for collectors..)
