Current Feedback Amplifier Kit - Assembly Parts and Manual
Bit Trade One Model AD00026
Compared to conventional voltage differential feedback amplifiers, current feedback amplifiers are less affected by speaker impedance fluctuations and can achieve a stable circuit configuration with less phase compensation even in wide bandwidths. They excel in signal response and phase characteristics, reproducing a smooth sound quality from low to high frequencies.
(From YAMAHA's website)
This technology is employed in single-ended vacuum tube amplifiers by feeding back to the cathode of the first stage. It is used in high-end amplifiers. I purchased this kit 10 years ago, interested in faithfully reproducing sound volume across all frequency ranges.
Although I bought the kit, I simultaneously purchased a used Marantz amplifier, so it remained unused and put away.
