Some Lyr owners really love these tubes–the same Russian NOS tubes we use in Valhalla. Of course, your results may vary! They also run warmer, so be warned–your Lyr will be putting out additional heat. They’re matched on a modern tube curve tracer, just like the JJs.
Tubes are covered by a 90-day warranty that begins when they are shipped.
Input Tube Type: NOS 6N1P tubes (Russian)
