So im giving a crack at trying to design something rather than just plug components into a pre designed kit ( not that I dont love that haha)
So I am working on a G pultec with a neve BA283 out put instead of the SRPP stage. I think I have a good topology going but I have never done this before so I obviously have some questions.
**attached is my proposed schematic**
here is my plan, have a step down transformer from 120V to 30V.=> (bridge rectifier)=> the use a voltage divider to take it down to 26V and then step it down again with a LM317T to get 24V.
I think this topology will work out nicely and be pretty efficient. thought?
my problem is the math. I am having trouble with figuring out the resistances for R1 and R2 (voltage divider) and R3 and R4 to tune the LM317T to 24V.
can someone help me with the math, I know its fairly simple but again Im not a designer or an electrical engineer, but I do want to learn!
