$69 pc.
12A max ripple pr pc.
could not find ESR. but i guess around 12mOhm
nice find
but also notice delivery, 17weeks
and I suppose you need pay taxes, etc
yes. i notised🙂 but this was just a quick search to point out that the price difference is low.
there will always be taxes🙂

may be a daft question, but will you notice the difference between staying 'safely' below 100V with say 90V, and taking the step to 110V ?
what if your load is 4ohm ?

+/-90V will give you around 800W at 4ohm.
+/-110V will give you around 1200W at 4ohm. wich is 1.5db. you will hardly notice it.
exept for some extra headroom. but something tell me you don't need that extra headroom 😀

I already got plenty of exstra headroom with 800watt 😛
which 10k resistor is rong in apex BA1200?plse help me...
Nothing wrong, just heat with 1,5W disipation.
btw, if anyone are interested in small caps, Nichicon 160V CS series seems pretty tough with 3A ripple for a cap size of 18 x 32mm (330uf)
and I have found a 3300uf 100V Epcos, at 15EUR (ø35 x 80mm)
due to space limits, and keeping a low budget, I go for good ripple current rather than large capacity

Nicely done, and almost fits in 3U of vertical position.

Thanks...what is the standard size of PSU board for 3U?

Try to fit it in 260x112mm, it's same dimension as amp pcb for 3U.

thanks before his designs are very nice and thank you to Mister Mile, if I may suggest for psu pcb design is also one that uses diodes as in the picture, because we were mostly diodes in place as shown.

hey ,thats nice job....bt i have 75 0 75v 1500va transformer....can anyone make the pcb of power supply with diode nd capacitor for my transformer??

You can use this circuit but with 120V caps instead 100V.
