It is a model from Uesugi Kenkuro, designed to function without amplification, resulting in a total gain of approximately 0dB, hence the name 'ZERO DECIBEL GAIN' amplifier.\u003c\/p\u003e\n\u003cp\u003eWhile it features no amplification, it incorporates a single 12AX7 (ECC83) vacuum tube. This tube is utilized for impedance conversion in a cathode follower configuration, contributing to the characteristic UESUGI sound.\u003c\/p\u003e\n\u003cp\u003eThe primary function of this unit is to act as a high-quality fader that prevents high-frequency degradation and serves as a tube harmonizer, even without gain.\u003c\/p\u003e\n\u003cp\u003eThis specific unit has been repaired as it was initially not powering on. It uses an AEG-made ECC83 vacuum tube.\u003c\/p\u003e\n\u003cp\u003ePlease note that the exterior casing has a yellowish tint that was present before purchase.
