Default CD player power supply suggestions (non-switching)

I'm just finishing off a basic power supply for a computer style CD player to
use as a stand-alone CD player with my hi-fi. I've built it in a computer PS
box, and so far it consists of two 20VA trannies, configured with 6v and 12v
secondaries. I've mounted a 78S05 and a 78S12 on heat sinks about 1.75 ins
square bolted to the case, and have used a bridge rectifier (100v, 3A) and
4,700uf cap for each supply. Before I hook up the voltage regs, can anyone
suggest any preferred circuits, parts, part values etc for the purpose (cap
values before/after the regs etc, or other solutions)? I'm assuming this won't
run too hot but again, suggestions welcome. The 20VA trannie for the 12v supply
is a bit tight, but I just happened to have some. Andy
