Triode TRV 88SER Valve Integrated Amplifier

KT88AB-class push-pull Integrated AmplifierTRV-88SER is a product which added slight improvement, remote control function and MM phono equalizer to popular TRV-88SE. TRV-88SE uses an integrated trans cover, but leakage from the power transformer has been improved by making it separate in this machine. Of course, it is a product with superior cost performance that exercises AB class 45 W + 45 W output as it is while maintaining the power that drives a low efficiency speaker strongly. This machine attractively reproduces the energy of mid-low range, which is a feature of KT 88, and the sound quality charm is exhausted to drive ability to faithfully reproduce jazz and contemporary pops etc.
