YAQIN MS 500B Vacuum Tube Integrated Amplifier or Power Amplifier, Class A, Single Ended, Tubes: 300Bx2, 6N8Px2,12AU7x2,5Z3Px1

• High Quality: all the components are at high quality level.Hand built audiophile output transformers with Japanese silicon steel and oxygen free enameled wire. Audiophile grade resistors, capacitors throughout and Japanese original ALPS volume Control.
• Easy Operation: you can find all the function operations on the the front and back panels, the UV meter, earphone output, infra remote control selection, signal selection, volume control, signal inputs jack, pre amplifier input jack, two channels signal output jack etc.
• Perfect Design : Pure Class A Triode single ended integrated tube amplifier with turn on delay protection circuit, vacuum tube voltage rectification, Infra-red aluminum remote control for volume and input selector.
• Solid Construction and Beautiful Appearance : the chassis is brushed anodized gray aluminum with machined and anodized gray grilles.
• Two Working Modes: work as an integrated amplifier or a power amplifers. Integrated amplifier is selected from Aux1-3 signal inputs, power amplifiers by Aux4 signal input as pure post-stage mode. This means Aux 4 can be configured to accept a preamplifier input.

Two working models (Optional):
Mode 1: AUX4 pure post-level mode as a power tube amplifier
Mode 2: AUX1-AUX3 signal inputs as an integrated tube amplifier
