Test Results Tube-1 = 800/950 Gm ( Coded I62 ≠3C ) Recent Feedback from our Fine Customers.... About Us Voltage regulators and line conditioners are used in front of our commercial grade
tube testers and our tubes are tested
twice on two different testers for accurate and consistent results. Our matched tubes have identical structure and we prioritize matching current because current is the single most important factor when matching power tubes! Then by Dynamic Mutual Conductance (Gm), the amount of use if any, and finally by logos and manufactured date. We also bias all of our power tubes as sets in one or more of our amps to insure they look and perform well together. Our
test results are
provided as a courtesy to help guide you in
determining the best product for your needs. We do not warrant that our
tubes will test the same or perform in any specific
manner when used and/or tested in your equipment. No one can truthfully
warrant this because of the variations in line voltage, interaction with other tubes and
components, different bias schemes and circuits, etc. We
do warrant that our tubes produced the results given in each
description when tested by us in our equipment and will perform
satisfactorily in your equipment as intended by the original manufacturer. No other warranty is
given or implied. tubo tubos tube tubes Rohr Rohre Rohren 管 管 チューブチューブ buis buizen rörsrören tabung |
