It's too bad you received bad advice. Tubes should be checked every few weeks or so for bias, and every time you install different tubes, they have to be biased.

The guy who bought my JOR , who actually owned 2 previous JOR's said the amp "should/ought" to be biased every year. Take that up with him. I figured he knows what he is talking about.
Good lesson learned.
