Can I jump in and ask a question (and please forgive my ignorance)??
My new internet buds on the ACC forum helped me rebuild an Acoustic Bass Amp. It's a simple Power Supply Design. The A/C Voltage is around 53 volts. That goes through the Bridge Rectifier and then connects to a 3900uf cap. The DC voltage is around 70 volts.
I'm trying to learn about power supplies, ripple, peak current loads, etc. I've often wondered, when does it make sense to use Chokes in a power supply? I came across an article that talked about an LC circuit and a Pi Circuit (Cap, Inductor, Cap) to smooth out the Ripple. Why is it that Guitar & Bass Amps do not use these types of filters?
If cost was NOT an issue, would it make sense to design power supplies using LC or Pi filters?
I'd like to study this further. If anyone has a reference to a web site or book on the subject, please post that here. And yes, I will read pages 167 - 193 of Teemu's book.
Thanks, Tom
