ARC CA-50 tube changing


Does any ARC CA-50 owner change their own tubes? If so, how do you bias the tubes? I've read comments that it's best to send the amp to ARC to get it done properly but I've had to bias amps before and I have a multimeter. There are no instructions for doing it that I can find. In fact, no user manual instructions. Anyone care to explain?

Yeah, it's kind of hard to see anything in there with the big 6550s glowing sideways and the boards mounted vertically on the sides. Still, if a tech can do it then why can't I? I just need some instructions...
Problem solved! I learned that my local second-hand audio dealer has lots of experience changing and biasing the ARC tubes. Echo Audio in Portland.

Thanks guys, i don't want to risk getting fried...
