[QUOTE="karpathion, post: 107377, member: 2449"] From how I read the biasing instructions, I think you are right about the 64mv on each test point, for the rt100. I've found a few other guys who have found the exact same thing in their RT series amps. The stock bias is just way different from what the instructions say they should be. Always a lot higher. I guess the best advise we could give to anyone purchasing one of these amps is, Check the bias as soon as you get it. I like the 503 I have to pieces, OD1 just does it for me. The only other problem I've had is a broken connection on the output of the reverb tank itself. It took about 10 minutes to get the tank out, solder the wire back, and put the tank back in. I just wish I could have a little verification from Randall, that the stock bias has been wrong, or the instructions have a little glitch in them. [/QUOTE]
