Spicy
You can make semi spicy into super spicy. Works well my only problem was upon start up the voltage spikes the drops to your set voltage. I’m hoping a cap filter might help with this.

Works
I’m not sure how accurate the multimeter is but wow. One of them was faulty.

Decent power
These work good with a 12v power supply. Good clean plate voltage and nice voltage range. 12volts is handy for the filaments.

They work, but may need some modding to work well
So far they work, but to comment:The good:They do work, voltage will adjustThe mixed:High ripple, I added a diode and cap on the output to run a 60v led filament. This mod makes a huge difference.Screw adjustment is touchy, also don't like making the adjuatments right near the HV outputs

Not for use around radios
I ordered these to make a 90 volt supply for a battery tube radio. They turned out to be extremely radio-noisey and un-useable for that purpose. I'll find another use for them.

Great value, works really well as a HV power supply for electrophoresis.
By combining this power supply module with a USB C decoy board and a digital volt ammeter it was really easy to create a handy little high voltage power supply. Definitely worth the purchase to get a 350V variable supply. BTW, this module delivers a + and - 350V so can actually deliver 0 to 700V DC!

These are an excellent option for charging high voltage caps.
Delivered exactly as shown, with extra capacitor on output. All work perfectly and at under $7 each these are best option on Amazon.

Not 390v but still good
The three boosters that I received are all outputting 155v to 170v, not 390v. Also minimum input voltage is 10v, not 8v. They still work great for the charging the capacitors that I have so I am not upset
