    101D direct thermal front stage

    Note:This amp is not includes any tubes,please know.

    1. This machine adopts a 12AU7 straight lotus-coupling push 101D transformer output (20K: 600 ohms) method.

    The power supply part adopts electron tube (any electron tube with filament current within 2.5A such as 5Z2P) mixed with transistor, rectified, filtered by 513 choke, and then used for power supply.


    2. The volume control potentiometer uses EIZZ 24 files 100K dual-channel high-quality stepping potentiometer (to ensure the consistency of channel separation and volume control). Connecting line Xidian oil wax wire, filter Xidian 513C capacitor and some antique resistors, etc. The 101 working voltage is 120V, and the current is 8MA per tube.


    3. Frequency characteristic 15H-40KH-2DB. The residual noise is 0.3MV.


    4. The sound quality of this machine is clear and transparent, the channel separation is high, and the sound is soft and durable.


    5. The size of the whole machine is 320*70*260, and the weight is about 9 kg.
