I check bias first day of every month on my ARC amp. Tubes from ARC, very little drifting.
First Test for tube bias on ARC Ref 110?
When is the appropriate time to first test biasing on the ARC Ref 110?
This is my first experience with a ARC amplifier and I have read that power tubes typically drift most in the early stages. What is meant by early stages? Any recommedations are appreciated. It has only just under 49 hours of use thus far, so far from even broken in yet...
