This little module delivers a split 800 Volt( -400, Gnd, +400 VDC) output ! It needs just over 10 Volts to start so it will not run from one 9V battery. Not sure of current output but charges 3Mfd capacitor to 800 volts in a fraction of a second...Nice

Great product and value. You don't want to touch the back of it when you first hook it up to your solar panel. It boosts well over 130 VDC.

This works as a power supply for small tube preamps. Maximum output power seems to be around 15 watts or so, intermittently. I'd trust it to supply about 5-7 watts steady state. I loaded it for 30 watts at 350v and it wasn't happy but it survived for the 30 or so seconds I had it on. You will require AT LEAST one 100uF filter cap on the output if you intend to use it for audio. Ferrite beads and a filter choke may not be a bad idea either, especially if you want to build a phono preamp. So it's a cheap way to get b+ on a small tube preamp, and maybe even a very modest power amp. Buy one. Buy 10. They're cheap so no worries.
