I think the heat sink of the SMPS can be smaller.

gev,

That looks sweet, dude! I can see you've used alot of parts from a pc supply. Very efficient. What is the controller? TL494? Transistors: BJTs or MOSFETs? What are the LEDs for? VU or headroom? Need info!!!!!!

You have to drill some holes to flexyglass cover up to the hetsink. Otherwise pc fan that you mounted rear panel will not find any air inside the box for taking outside.

However, yo have done a nice job.

Wow

Very nice one.

It seems like the case does not provide any shielding.
Any problems?
