I've used the RG and RF-linx amp together with a 15V 1.1a ps.
I tried an 18v 1.5a for about 2 weeks, it worked fine until one day...it
just stopped working. I power-cycled the setup...but it wouldn't come back.
So..I put a different PS on (the 15V one) and it started working again. I
guess I never checked to see if my PS was bad though.
