Product Description & Reviews
Parameter: Note: this is a DIY kit, all the components will need yourself to solder it. This is the pre-tube, can not directly push the box, can not directly push headphones AUDIO NOTE M7, is a well-known, nice guts; PRT-02A reference to the amplifier circuit, so that new students can also spend a small amount of cost-effective H products. This version is compatible with the design, through the jumper on the PCB for different tube adaptation, work voltage: 0-AC(6-12V) above 1A. (when above AC9V. please note the heatsink temperature) 0-AC(200V-240V) above 10mA compatible: Jump cap shorted A1 = 6N2, 6N11, 6922 and other 6V power supply tube (6N1 current is too large, not suitable) Jump cap shorted B1 = 6N4, 12AUT, 12AX7, 12AT7 12V power supply tube The PRT-02A is designed as an integrated board with DC filament power supply, high voltage band regulation and electronic filtering. Voltage input requirements: Filament part: AC6-12V not less than 1A (when more than 9VAC input, please pay attention to heatsink heat) High-pressure part: AC200-240V, not less than 10MA OUR supporting small EI transformer Size: 127X75X80 (with copper column and tube height) Special Note: In order to reduce the internal resistance of the high-voltage part of the power supply, this version is not designed to install the discharge resistor, so the high-voltage part of the discharge after power is extremely slow, do not touch the high-voltage part of the device Package: 1 pc PRT-02A Tube Preamplifier Kit - Includes Tube
