Precision Matched Power Tubes

Accurate power tube matching can minimize the risk of early tube failure and maximize power tube performance in your amp. All our premium matched new production power tubes are:

  1. Burned in. After performing thorough tests before and after burn in, we have found that the change in readings for current draw, transconductance, and gas was significant enough to require a 48 hour burn-in period for accurate matching.
  2. Tested at typical operating conditions. Click "more info" for any of the power tubes listed below to see the voltages we use for our standard testing and matching. If the operating conditions for your equipment differ significantly from our standard voltages, we can custom match power tubes to your specifications.
  3. Matched for both current draw (mA) and transconductance (Gm). We are almost always able to match new production tubes to within 1-4% on both scales. This takes more time on our part, but we feel the benefits are worth it.
