I recently acquired an Origin 50c. I love this amp and am very happy with it. I have been looking for info regarding tube replacement. I have found several places that indicate the Origin 20 is self biasing, but have seen conflicting info on the 50c. Does the 50c need rebiasing when replacing tubes?
Thank you
Hello Martin,
The ORI50C does need to be biased when the power valves are replaced.

Thanks for the clarification!
