I too have a Cary V12R and the bias should be about 238. I need new tubes so I'm going for a full set of Rubys. 2 AX7's and 2 el-84's. The amp just makes a loud hiss when I flip on the operate switch on the Cary SLP98P, so I must have 1 or 2 bad tubes. I have moved some of them around and it does not help. The system sounds great when it works, and the amp does run hot normally.
