Yep, it's working.
That looks like a nice little preamp.
Here's a preamp I built.

Hi corndog !
(Funny nick-name you have !)
Nice pre-amp you have built. I like the color, it gives a hi-class look.
My wife doesn't like the knobs, she says they look like BBQ gas stove ! ! ! Don't pay attention to what she says, what does she know about audio equipment. (Ha, ha...)
By the way, my Niteshade Audio SE-15 is a Single Ended 15 wpc integrated amplifier, not a pre-amp.
Soon, I will post my comments on how the whole system sounds.
Have a nice weekend.
