Finally all connected!
Getting the amp and preamp was touch and go. Even though both boxes were shipped together, they arrived at different times.
Preamps were not delivered because my place was seen as vacant. Well, yeah. I was moving in the next day. Tracking said returned to sender. Yikes!!! Fortunately, I was able to intercept the box at the post office.
And the amp... Was out for delivery today, and all of a sudden, tracking said, "No such address. Return to sender." I was able to intercept it, too. It was addressed properly, but whatever. Just glad I got it all in good condition.
