Provides 200V under no load, but output drops to near zero volts under even light load (a few 10s of mA.) Review: Works well to power small guitar amp - I like this. I am using this to power a small vacuum tube amp that I built for my guitar. I can not crank to full voltage but I can get it up to about 200 volts and it runs a little warm but is stable and does not introduce noise into the amp. This works much better than having to have a high voltage transformer etc. You can run this off 12v batteries and get off the grid and play a tube amp without heavy transformers etc. ## Features - DC12V Boost Converter High Voltage Filament Filter Power Supply Board, with a set of filament and a set of high voltage, two sets of voltage adjustable. [Note: The higher the output voltage, the lower the output current. This has nothing to do with product quality.] - Input voltage 12VDC, Output high voltage 150V-420VDC and 1.25V-12V DC filament voltage regulator is adjustable. - Due to the use of high-frequency switch, no effect on the audio, signal to noise ratio is very high. - PCB Size: 90x55x32mm/ 3.54x2.16x1.25inch(LxWxH) (Note that the size of the filter capacitor may be different, and the parameter value is the same, and we will ship it randomly.) - 20K potentiometer can adjust filament voltage (1.25V-12V DC, max 3A) ; 30K potentiometer can adjust high voltage voltage (150V-420V DC); 1K potentiometer(near the heatsink) can adjust high voltage current (30-40 mA). ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0992GCCSK | | Best Sellers Rank | #599,082 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #2,789 in Power Converters | | Brand | QINIZX | | Brand Name | QINIZX | | Current Rating | 3 A | | Customer Reviews | 2.9 out of 5 stars 34 Reviews | | Item Highlight | 170V 230V Output, 6.3V Filament Adjustable, 2-Way PSU Regulator Module, Step Up Power Supply, For Tube Preamp/Nixie Tube | | Item Weight | 4.16 ounces | | Manufacturer | QINIZX | | Maximum Frequency | 80 KHz | | Minimum Frequency | 80 KHz | | Model | 12VBoost-HVPSU | | Mounting Type | PCB Mount | | Number of Items | 1 | | Number of Packs | 1 | | Part Number | 12VBoost-HVPSU | | Power Source | Corded Electric | | Specification Met | CE | | UPC | 723258876523 | | Unit Count | 1 Count | | Warranty Description | 90 Day Manufacturer | ## Product Details - **Brand:** QINIZX - **Current Rating:** 3 A - **Mounting Type:** PCB Mount - **Power Source:** Corded Electric - **Specification Met:** CE ## Images ![High Voltage DC-DC Boost Converter 12V to 150-420V & 1.5-12V Step Up Power - Image 1](https://m.media-amazon.com/images/I/6102IBFQNbS.jpg) ![High Voltage DC-DC Boost Converter 12V to 150-420V & 1.5-12V Step Up Power - Image 2](https://m.media-amazon.com/images/I/61UoyXdkiES.jpg) ![High Voltage DC-DC Boost Converter 12V to 150-420V & 1.5-12V Step Up Power - Image 3](https://m.media-amazon.com/images/I/61hntcXp+JS.jpg) ![High Voltage DC-DC Boost Converter 12V to 150-420V & 1.5-12V Step Up Power - Image 4](https://m.media-amazon.com/images/I/61ezJxDr-zS.jpg) ![High Voltage DC-DC Boost Converter 12V to 150-420V & 1.5-12V Step Up Power - Image 5](https://m.media-amazon.com/images/I/61O1Hy9iU+L.jpg) ## Customer Reviews ### ⭐ Poor quality *by T***R on June 12, 2026* Worked well for a very short time, then failed.
