Description: 6BE6/EK90/X727 Mullard Vacuum TubeGray PlateTop Square Getter Tested at 68on a calibrated B&K 747B tube testerwhere the Good range is 65-120 *B&K 747B calibrated *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)Not tested for noise or microphonicsTest 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 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 like sections of a set of tubes. 'Matched' I consider to be within 10%. 'Closely Matched' I consider to be within 5%. 'Tightly Matched' I consider to be within about 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 .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.
