- 6N3P-E is a VINTAGE Russian dual-triode 9-pin vacuum tube that was manufactured by the original Reflektor plant in Russia. This long-life tube (denoted by the "E" suffix) has 3 mica-spacers and is considered an exceptional audio tube.
- Tested and Matched using Amplitrex AT1000 tube testers to evaluate the electrical parameters of the tubes.
- Data labels for Gm (mutual condutance), Vg (grid voltage) and tube gain (µ) are attached to the tube boxes (tested using auto-bias mode). The tubes chosen for these special matched-pairs have very good balance between tube sections and close electrical parameter matching between the tubes. Tubes are matched within 6% for Gm, Vg and tube gain. Individual matched pairs will have identical manufacture date-codes.
- 2-year warranty. All Platinum Grade vacuum tubes are backed by our no-nonsense two-year warranty. We also guarantee that the tubes selected for our matched pairs test at NOS levels. For protection during shipment, we use tube boxes designed by Riverstone Audio (our “Tube Cradle” boxes). Vacuum tubes sold by Riverstone Audio will have the "Riverstone Audio" name, logo and QC label on the boxes.
