I have built this little supply designed by Pete Millet it works very well.
If you don't want to build a point to point circuit he offers p.c. boards
for it on ebay.

That heatsink isn't going to support the required dissipation of this application unless you're willing to have a fan blowing on it.
What kind of amp do you have this installed in ? Did you do a comparison with other methods of heater supply in your amp? In my case the amp will be probably my most ambitious project so I am trying to have the best possible circuits while keeping costs within reason. cheers, Dak
You don't want to DIY a SMPS.I did a 10V/3A regulated DC supply not all that long ago. It required a heatsinked bridge of TO-220 diodes, a heatsinked regulator, three heatsinked beefy transistors, a bunch of lytics, and about 10 or so 5-10W resistors.
The SMPS is a lot more economical and space efficient.
