Amp Preamplifier Tude Regulator power supply PCB Board (6V6 6P6P EL34 6P3P KT88)
Description:
Low-voltage (16V) zener diodes are used for the gallstone-mixed, wide-range voltage regulation and regulated amp power supply. This power supply has a wide voltage regulation range, excellent voltage regulation performance, low output ripple, and flexible adjustment options.
Regulator D3 can be selected from a wide range of 10~20V/1W. However, it should be noted that when the selected regulator voltage regulator value is below 14V, R5 should be changed from 12K to 8.2K, otherwise it is possible that R4 will be adjusted to the minimum and the maximum voltage regulation output will not reach 360V.
