If you are familiar with the improvements of the QSA fuses and adapters, then it is easy to see that a logical next step would be the treatment of vacuum tubes. QSA treated vacuum tubes offer the enhanced musicality and resolution of the QSA treatment for the integral parts of your tube based components.
QSA offers PSVANE Classic, Linlai (power tubes) and Genalex Gold Lion vacuum tubes treated with their proprietary process. The warranty for PSVane is 12 months, and for Linlai it is 14 months. Pricing is in pairs.
In addition, we may be able to treat NEW tubes you supply. While we will take the utmost care in the shipping and treatment of your tubes, we cannot guarantee your tubes will survive shipment, or processing. We are not responsible for damaged or broken tubes that you send for treatment.
QSA will only warranty new tubes that QSA supplies and treats.
