"as the bias window on any amplifier should never be so wide as to do damage to a tube."
Actually, a too narrow adjustment range causes more trouble (of a different type). Keep in mind that current variation from tube to tube of the same type/brand/etc. will be over 100%. So a wide range of adjustment is needed.
The best solution is to remember to turn the bias WAY down, down near the lowest current position - then install the new tubes and bring the bias UP to the current spec. That way the bias you had on the older more heavily worn tubes won't be there to allow the new tubes to go over current.
