Other Notes: Decidedly retro, the 300B harkens to a bygone era that focused on the simplicity of design. Expect luscious mid range, delicate detail, and seductive emotion. User control of negative feedback and the ability to switch topology ‘on the fly’ from 12 Watts in parallel SINGLE-ENDED mode to 25 Watts in PUSH-PULL mode is totally unique. This is an amplifier that will always delight and entice you as it adapts to a variety of efficient speakers (and ears!).

"Manley designed the 300B's to be very user-friendly and also to be as versatile as possible. There is a speaker impedance matching toggle switch on the back of the chassis. One setting allows for speakers with impedance ratings of 4 Ohms to 12 Ohms and the other setting is for speakers with impedance ratings of 12 Ohms to 20 Ohms. Manley also allows for selecting Single Ended or Push-Pull settings "on the fly". In Single Ended mode both 300B tubes are used in parallel, resulting in a minimal amount of circuitry in the signal path, but the result is a lower power output. In Push-Pull mode, according to Manley, "each tube works in opposite phase to the other and relies on the output transformer to make the polarities work together. This has advantages in efficiency and in the distortion and noise cancellation properties of a balanced circuit." - AVRev
