I have this burning desire to modify my CD player, and maybe learn
something along the way.  I am in the process of replacing the op-amp
section with the POOGE-4 mods.  The Audio Amateur's advice for the
adventurous is to add another power supply to the player (A magnavox.)

I am going to use the same transformer, and split the supply from
rectification on down.  Here's my question:  The current power supply
goes like this:  Transformer -> rectifier -> large cap (150uF) ->
regulator (78M15CT) -> small cap (47uF) -> 15V out. 

If I want to improve the quality of this set-up, should I change the
topology at all?  Can I just make the Caps bigger?  Any other advice?

Well, that's all--  Oh, does anyone have advice about good books on
subjects like this, and possibly audio electronics as well?

thanks,
