I did not because I don't have it connected to the antenna right now. However, when I did have it all hooked up, I unplugged the power source for a little while and my reception went to zero. Plugged it back in and my reception went back up. I'm assuming that means the amp was getting power.Congratulations!
Did you check if your existing amplifier gets DC power?
Just finished my 8-element coco and I'm about to hook it to the receiver, but I have a couple of things to do first. I'll hook it up with the next hour or so. I had to run to Walmart to buy a new multimeter because my old one gave up the ghost after 30 some odd years. The element broke off one of the probes so I took it as a sign that I was due for a new one. New one has digital display.
