Low Voltage Regulator (Filament Supply for Landfall Heatsink)
This is a low-voltage regulated power supply, intended to be used as a DC power supply for tube filaments or heaters. It's substantially the same as the other filament regulator I designed, but it's re-packaged so it will fit in the Landfall Systems heatsink, which gets the heat dissipated up and out of the chassis. Here is the schematic(or download it as a PDF file):
For more information, see the other regulator web page.
Here is the PCB, available on eBay:
The assembled PCB:
Contact Landfall about the heatsink. You can also get a prototype bard from them that lets you build your own circuit using this heatsink.
Note that you need to space the power devices such that the bottom of the plastic body is about 1/4' above the PCB, so that the heatsink and clips correctly mate with the heatsink.
You can of course use some other heatsink method if you prefer.
