Cayin MT-50 Plus is a tube amplifier, hand-made with the finest point-to-point wiring. Equipped with specially designed toroid transformer for power supply and two EI output transformers with wide bandwidth. 

Audio grade Takman carbon resistors are used for a better sound. The voltage amplification is done by 5BK7A tubes while the RCA 25AX4GT rectifier tubes are used for independent power supply. Four KT88 tubes are used for Class A-B push-pull amplification.

The amplifier is designed with Triode and Ultralinear mode selection. With Triode mode, you can experience a warmer, more vocal-centric sound. With Ultralinear mode, the sound is more bold, open and you can experience better details in the sound. External BIAS adjustment is accessible by the user, with the BIAS meter for monitoring on the top of the amplifier.
