1. I know I have to change ZTX450 and ZTX550, do I need to change Electrolytic Caps C3, C4, C7 for a higher voltage Rating?
2. Is Mouser Part# 527-NK202C2R5 a good option for R24 2K Thermistor?

I bought a pair of these Blocked But then I bought the output devices from Digikey too (2SA1695/2SC4468), so saved on the postage

I bought KSA1220/KSA2690s from Digikey too, but out of stock now

Any suggestions on a good Power Supply Design ?

Thanks in Advance!

Thank you all for your replies and help so far, I’m not even close to done (not even started), so I’ll have to keep bugging ya’ll...

As I try to design the Welder Power Supply I’ve been looking at Antek Toroidals and I found Papa’s comment (picture) in a post, I guess that’s enough for a blessing?

Is there any other brand that won’t break the bank, fairly priced like them that you can suggest?
