Good afternoon

 

[Monk55]

Should work fine. I’m using Nichicon LKG1H682MKNS which is pushing the voltage a bit.
I’m trying to build a PCB for the tube & it’s a pretty good learning curve using Kicad for the first time.

As heatsink, would this be enough for the lateral Mosfet?

Solid State Relay Heating Radiator 110X125X135MM be used for Three phase solid state relay 10A 25A 40A 60A 80A 100A 120A 150A|Relays| - AliExpress

Thanks

That look just like mine but the price is way better. So it appears adequate

I think/hope this will work & it’s off to fab.

Monk55, where are you buying Lateral MosFets?

It does grow majestic 🤩

My 500 watt light measures 2.6 ohms. That may need help.

Thank you Michael R. For the pictures.
