Description: BalancedJTL 5687 Tung-Sol NOS 1957 Vacuum TubeBlack PlateTop D GetterTested at 79/79 on a calibrated TV-7D/U tube testerTV-7 Avg. Minimum = 38 *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 calibratedTest 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 when I next check my ebay account*If your purchase is not fully satisfactory please contact me .International customers welcome: Please do not ask for false value on the customs formFor combined international shipping you need to send an email listing the items you want to buy and I will create a single listing for all the items that you can buy with the corrected shipping charge*Tubes will be shipped in a cardboard box with packing, usually bubble wrap or sheet foam Packed for protection Packed for ease in unpacking *Tubes will generally be cleaned Clean tubes will radiate heat better & operate cooler *Pins will generally be straightened/cleaned as needed Cleaned pins make better electronic connection *Most tubes are shipped in their boxes (or replacement boxes) I often repair a box so it will function properly*I try to get your package in the next mail after receiving your order.
