It has a few mV of noise which is load dependent. In my case I am using this in a supply for a measuring microphone. The mic needs super clean 120V at a couple mA, and super clean 200 V at no current. To clean the output up I used a Sziklai pair capacitance multiplier to get the noise down into the uV range plus an RC filter for the polarizing voltage. **Q: Schematic of this product.** A: I was not able to find a schematic for the power supply circuit. Would have to reverse engineer the board to get the circuit. **Q: What is required for it to work?** A: A 12 volt DC 1A wall wart powers this just fine. **Q: Exactly what type of transformer is needed for the high voltage dc-dc boost power supply converter module?** A: All you need as a "wall wart" that plugs into the AC wall socket and delivers 12 volts DC. Cut and remove the coax plug from the wall wart's cord. Check polarity and connect the + lead with to red and - to black. A wall wart rated at 1 amp is enough as long as your HV load does not draw more than about 30mA. By the way, 30mA is about the limit for what this board can do before the inductor's core saturates and the efficiency goes way down resulting in overheating. ## Frequently Bought Together - High Voltage DC-DC Boost Power Supply Converter Module for Vintage Vacuum Nixie Tube, Magic Eye 6E2 Level Indicator 9V-12V DC Input, 80V-380V DC Output (Green) - 1Set Dual Way Magic Eye 6E2 Tube Audio Level Indicator Module VU Meter Music Spectrum Vacuum Tube Level Indicator Driver Board DIY Kits - Acxico 2pcs Beijing 6E2 Electron Tube Magic Eye Tube Fluorescence Tuning Indicator Tube --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/368484753-high-voltage-dc-dc-boost-power-module-for-vacuum-tube](https://www.desertcart.vu/products/368484753-high-voltage-dc-dc-boost-power-module-for-vacuum-tube) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-08-19*
