F-300B EVO

About the F-300B EVO

The Finale Audio F-300B EVO is a handcrafted, reference-grade stereo integrated valve amplifier using a Class-A single-ended-triode (SET) 300B output stage with automatic bias. It is designed around a pair of 300B output valves, a pair of 12AX7/ECC83-family input valves, and a pair of 6N6/6DT8/6FQ7/6CG7-family driver valves. The EVO specification incorporates Hashimoto Japan 20 W classic output transformers, a Hashimoto choke transformer, and a proprietary Hashimoto-built 300B power transformer. Other stated parts include an ELMA Swiss input selector, ALPS Japan volume control, two Finale Audio Pink-Lingu rose-gold-plated RCA input pairs, Furutech gold IEC AC inlet, and CMC gold speaker binding posts. It delivers approximately 8 W per channel and is intended for efficient loudspeakers. Published performance can vary somewhat with the installed 300B and rectifier valves, as well as transformer configuration. No DAC, network-streaming, Bluetooth, phono, or headphone-amplifier functions are specified.
