LTSpice model of BHL MC head amp...no output

I modeled the Boozhound Labs moving coil head amp using the LSK170 model that comes with the latest distribution of LTSpice (add njf, place > pick new JFET, choose LSK170). I didn't define anything past that.

With 0.3mV in, I get no signal past the drain. There are no open lines.
18VDC voltage supply.
Do you see any errors?
Any possible missed steps?

This is my first solid state circuit simulation. I usually work with tubes.

Thank you for your input.

Hi,

I' d say ... no supply no cookies 😉
The voltage source's positive pin needs to be connected to R5.
Its negative pin goes to gnd.
At the output the resistor is just one milliohm.
1M has to be marked as 1Meg.

YES!!!

Thanks!

The power supply -- I knew it had to be something idiotically obvious.
"Meg" - it's been a while since I used LTSpice. Thanks for pointing that out too.
