Kondo AudioNote Japan Gakuoh - II (NEW)

The amps produced in April 2020

• New Generation original OPT for optimized 300B bass extension and vocal fidelity
• Improvements over classic 300B amplification circuit plus modern features
• Dual GZ34 rectification and strengthened power supply design
• New flagship silver signal capacitors and parts (applied also to Kagura, G-1000 and GE-10

Input stage is plate follower and direct connection cathode follower by 6072. Classic type phase inverter circuit is chosen for good balance of naturalness. 300B power tubes are fully driven with low impedance by 6CG7 in parallel configuration.
By suppressing overall NFB to only 2 dB, a new level of dynamic and low distortion is achieved. Sound quality is also improved through adding high quality resistors in combination with the VR of hum balancing circuit. 300B output stage is self-biasing circuit. This help owner to replace various kind of vintage 300B without stress.
Smart modular design and shortest wiring set good foundation for Gakuoh II's long durability with good sound.
