RCA microphones are tried and true classics, from the very first production ribbon microphones in the world ("Photophone" Type PB-31) to the utterly ubiquitous 44-BX and 77-DX that fill the mic lockers of all major recording and scoring studios. RCA was also a major force in the world of electronic parts, particularly vacuum tubes, and NOS examples of octal-base RCA tubes continue to fetch premium prices among tone-chasers. Shop Reverb's collection of used and vintage RCA microphones and parts today for the best deals on that rare gem you've been waiting for.
