Why Black Plates Matter
RCA 6201 is the ruggedized military version of the 12AT7—built for extended service life and high vibration tolerance. Black plates deliver warmer, richer tone versus later grey plate versions. Ideal for phase inverters in Fender/Marshall-style guitar amps or driver stages in hi-fi equipment.
