Matched Pair 6SJ7 Sylvania NOS Same code = CR/AAE Vacuum Tubes These are the big boys Tested at 67 & 70 on a calibrated TV-7D/U tube tester which is 108% & 113% of TV-7 Avg. New Avg. Min. (65%) TV-7 chart & Avg. New (100%) = 40 & 62 *We use the following testers: *Dan Nelson calibrated TV-7D/U with sweep tube adapters, & digital meter with plate current test at 150V. *Paul Hart calibrated/modified Westmore 501 (Triplett 3444) * B&K 747B calibrated Test results may differ between various testers for many reasons such as technical design, aging components, etc. So while test results are a good indication of quality there can be some difference between the many differently designed & maintained testers. The following definitions are mine as I use them. ‘Balanced’ refers to comparing the gm test results between the lowest to the highest identical sections of a single tube. Within 3% I consider to be ‘Balanced’ ‘Matched’ refers to comparing the gm test results between the lowest to the highest of the identical sections of a set of tubes. ‘Matched’ I consider to be within 10%. Some call similar ‘Gold Matched’ ‘Closely Matched’ I consider to be within about 5%. Some call similar ‘Platinum Matched’ ‘Tightly Matched’ I consider to be within 2%. *For Multiple item purchases click the “Add to Cart” selection for each item *After all items have been added to your cart click on “Request Total From Seller ” *An invoice will be returned with the correct ‘combined shipping’ & total due * If your purchase is not fully satisfactory please contact me .
