Hello,
I am in the basic building stage (just trying to understand the concept)....
I have not made any purchases yet.
I plan on building a Class A, Class B, or Class AB amplifier in the next few months. I have many steps to take before that .. This is step one form me.
From what I have read so far...I am having trouble finding formulas to prove the this basic design. ....see attachment...
1. Should I use the bridge rectifier? I can't seem to understand what the max spec values really mean.
2. What size in uf capacitors should I use and why for filtering?
3. Will the capacitor values affect anything other than filtering?
4. What is the calculated current available for the output?
5. Once loaded down, should the +20V rail have the same load value as the -20V rail?...I plan on using the positive rail for some other 12v and 5 v regulator to drive small sub circuits.
6. Any other design considerations that I should research, modify, or evaluate?
