Biasing problem????

130.13.84.84

I'm attempting to bias my Almarro 318A amp. bias voltage is supposed to be .18v DC. I can get one output tube within range, but not the other. I switched output tubes around and the bias problem followed the tube. Do I need a matched pair? Is one of the tubes bad? Thanks!
