CF-i300B

CF-i300B Integrated Amplifier

The CF-i300B is an all-tube integrated amplifier featuring a pair of the 300B output tube driven by a pair of 6SJ7/6SJ7GT/5693. Rectification is handled by a 5AR4/GZ34. The directly heated triode amp outputs 9 watts/8ohm per channel. The circuit topology is extremely simple and signal paths are short.
The CF-i300B has four sets of single-ended inputs and one of them can be switched
to balanced (XLR). Users can select the speaker output impedance between 4 ohm and 8 ohm. As a bonus, it has a solid-state headphone amp which can drive either pair of a single-ended or balanced headphones.
