Description

WZ-17 Tube Pre-stage High-Voltage Regulator Power Supply Board Ma7 Power Supply Feature: Finished board with an imported dismantled LM317/TIP50, because the new environmentally friendly package, the quality has decreased, the dismantled heatsink is thicker, the output current capacity is stronger, the withstand voltage is more guaranteed, care about this caution to buy. In order to facilitate your installation and debugging, with the board is equipped with circuit diagrams and component list. Note : Our finished board before sending is adjusted to about +280V output. Suitable for Marantz VII and so on. After you receive the board can be adjusted to the desired value, or tell us to help you adjust to the desired voltage and then sent. This board output high voltage can make the value of about +150-350V range adjustment (please pay attention to the capacitor withstand voltage and pressure difference), need to be lower or higher, please follow the instructions to change the value of their own components. Finished boards are adjusted to about DC280V before sending, after you receive it, please adjust it to your own desired voltage. Finished product size about: length 106mm, width 75mm. Maximum height of about 30mm, easy to install into a short chassis or rack above the original PCB. Special note for newbies, this AC input place is to add a transformer, not direct utility ！！！！ This board circuit is anatomical horseshoes, designed for bile preamplifier and other small current power supply design, amplifier and other places are not suitable for use. Our long time test conditions are input AC230V, output DC280V, current 30mA. This current is enough for 99% of the bile preamplifier, of course, the current is too large can also refer to the original machine, with 2 pieces of dual-channel power supply separately. If a small change, the current can be a little larger, we will have instructions with the goods.
