Philco 6L6GT

The Philco 6L6GT is a vintage beam power tube, commonly used in audio amplifiers, radios, and early guitar amps. As a 6L6GT type, it features a glass envelope (the "GT" stands for "Glass Tube") and typically offers warm, rounded tones with solid low-end response.

Made by or for Philco—a historic American electronics brand—these tubes may have been manufactured by major tube producers like RCA or Sylvania under Philco branding. While not as collectible as some premium labels, vintage Philco 6L6GTs are still appreciated for their solid build quality and classic American tone.
