Remember:

Every tube gets:

1. Burned In (Less drift when biased)
2. Tested
3. Matched

» Burning In

All power tubes are burned in for 24-48 hours using a pair of Maxi-Burn rigs that each burn in 30 tubes at a time. Burning the tubes in stabilizes the tube, which ensures a more accurate reading for when we match the tubes.
