Wow, I've never built a diy SMPS yet.
Mile, would you use this design on a solid state amp?
Do you maybe know of a diy switch mode supply for a SMPS for a dual 150W into 8R amp ?

Thanks for all you share

Hi Apex .
I use Sendust core PS184026 , AL = 26, Values we need is = 33uH.The formula for calculating it
n =SQRT(nH/Al) = =SQRT(33000/26) = 36 turn. Check again by Multi Meter OK. Can you recommend me a good MostFet ?
Thanks Apex.

Some pictures of Apex D200. I am testing it with +- 35VDC an its play loud with stong bass. The high are a little too agresive for my taste ,but for the my first D class amp its OK.Fets are just a little warm the coil is at room temperature, all in all very good.

Hello Apex,

D200 rev. lay-out don't have 100nf/100v near the resistor 4.7k/5watt, while the lay-out of D200.2rev has and what the different in adding 100nf in D200.2?
