Integration

Connecting this to the various inputs and outputs is also super easy. The in and out pads are obvious. There is one more

pad I probably should have labeled "gnd" that is for a wire to connect to the chassis, ideally at a ground lug where you

connect the ground wire from your turntable.

The pwr pads need to be connected to a source of roughly 24 volts filtered DC. There is a bit of filtering (more like

decoupling) on the board, but not enough to filter AC. I use a mid-grade switch mode wall wart power supply for this

because they are cheap, easy, and very quiet. An upgraded regulated power supply would be a nice upgrade I'm sure.

There is no onboard fuse. The wall wart power supplies I imagine almost everyone will be using for this are internally

current limited. If you use another power supply, a fuse might be a good idea. Current draw is less than 50 mA.

I include the standard 47k load resistor, but feel free to change that to something that is better matched to your

cartridge or stepup transformer or whatever.

The mounting holes at the corners are designed for 4-40 thread screws. The boards measure 5.3" by 3.5" by 1.25"

Now go play a couple of those Steely Dan albums you buy every time you see them in the thrift store!
