Tubes initially drift quite a bit from their correct bias point.
For this reason, it is always suggested that you retube with burned-in tubes. This means that a new tube will change its characteristics quite a bit, and that once a day or two of use is on the tube, that the characteristics will stabilize to a large extent. This is very important to understand and use. Over time your tubes will require a different correct bias voltage in order to run at optimum performance. Failure to keep tubes properly biased can reduce an otherwise fine tube's lifespan by years.
