Platinum Tubes New Old Stock / New In Box U.S manufactured Western Electric 300B Triode PAIR Normal 0 false false false EN-US X-NONE X-NONE Tubes are tested and will be supplied with individual test reports. They have slightly higher plate current characteristics and therefore are considered as B stock. With proper Bias adjustment they can be adjusted for excellent performance in high end Audio equipment. Each tube will be supplied with a six month warranty. Satisfaction guaranteed ! Buy these tubes for 50% of the normal W.E. price with the same fantastic W.E. performance! SOUND QUALITYThe 300B is known around the world for its sound quality and powerful performance in both single-ended & push-pull amplifiers. THE ORIGINALThe original 300B is made with authenticity and precision. Listeners have trusted the same specs, materials, and testing standards for over 80 years. Balanced, Powerful, RefinedThe WE 300B sound is balanced, powerful and refined with quality bass from the lowest frequencies through the upper bass. The midrange above is a thing of beauty; dulcet tones, seductive vocals, instruments of all types dimensional and present, all heightening the participatory elements of music.Burnished and Beautifully SeductiveHigh frequencies are at once transparent, lovely, sweet, burnished and beautifully seductive. The air and space between performers are extraordinary, performers appear on a quiet and focused soundstage whose width and depth are masterfully rendered. You don’t have to search to find the sweet spot with a WE 300B amplifier, it’s all around you.Find out what tube aficionados all over the globe know, the WE 300B is the most natural, elegant and emotive triode anywhere in the known universe. Classification Moderate power, filamentary triodes for Class-A service.Application Audio-frequency amplifier in positions where power outputs of approximately ten watts or less are required at relatively low plate voltages.Dimensions Dimensions, outline diagrams of the tubes and bases, and the arrangement of electrode connections to the base terminals are shown in Figures 1 and 2.Base and Mounting These vacuum tubes employ medium, four-pin thrust type bases suitable for use in Western Electric 143B or similar sockets. The 300B tube has the bayonet pin so located that it may also be mounted in a Western Electric 100M, 115B, or similar socket.The tubes may be mounted in either a vertical or horizontal position. If mounted In a horizontal position, the plane of the filament, which is indicated In Figure 2, should be vertical.Average Direct Interelectrode Capacitances Grid to plate 15 µµf. Grid to filament 9 µµf. Plate to filament 4.3 µµf.Filament Rating Filament voltage 5.0 volts, a.c. or d.c. Nominal filament current 1.2 amperesThe filaments of these tubes are designed to operate on a voltage basis and should be operated at as near the rated voltage as possible. When alternating current is used for heating the filament, the grid and plate returns should be connected to a center tap on the secondary of the filament transformer. CHARACTERISTICSAverage Characteristics (Ef = 5.0 volts, a.c., Eb = 300 volts and Ec = -61 volts) Plate current 60 milliamperes Amplification factor 3.85 Plate resistance 700 ohms Grid to plate transconductance 5500 micromhosRecommended Operating Conditions Recommended and maximum conditions for alternating-current filament supply are given in the table. Recommended conditions or others of no greater severity should be selected in preference to maximum conditions wherever possible. The life of the tube at maximum operating conditions will be shorter than at the recommended conditions.Where it is necessary to operate the tube at or near the maximum plate current of 100 milliamperes, provision should be made for adjusting the grid bias of each tube independently, so that the maximum safe plate current will not be exceeded in any tube. Alternatively, a self-biasing circuit may be used, in which the grid bias for the tube is obtained from the voltage drop produced by the plate current of that tube flowing through a resistance.Where it is necessary to use a fixed grid bias, the plate current of the average tube should be limited to a maximum value of 70 milliamperes, so that tubes having plate currents higher than the average will not exceed the maximum safe plate current.Power Output and DistortionPerformance data including power output, second and third harmonic levels for a number of operating conditions are given in the table.The variation of power output and harmonic levels with load resistance for several values of operating plate current is shown in Figures 7, 8 and 9, for a plate voltage of 350 volts.The peak value of the sinusoidal input voltage, Egm, which gives the indicated power output, Pm and harmonic levels, F2m and F3m for each point in both the curves and the table, is numerically equal to the grid biasing voltage at that point. For a smaller input voltage Eg, the approximate levels may be computed from the following relations.P=Pm(Eg/Egm)^2 F2=F2m+20 log10(Eg/Egm) F3=F3m+40 log10(Eg/Egm)CHARACTERISTIC CURVESPlate-current characteristics for a typical tube are shown in Figure 3 as functions of grid bias, for alternating-current filament supply. The corresponding amplification-factor, plate-resistance, and transconductance characteristics are given in Figures 4, 5 and 6, respectively. When direct-current filament supply is used, and the grid and plate returns are connected to the negative end of the filament, the same characteristics are applicable if 3.5 is subtracted from the numerical value of each grid bias. WHY PLATINUM TUBES? Why Platinum Tubes? Deep Expertise: We understand the unique demands of tube technology and offer a comprehensive selection of parts for top brands. Quality Assurance: Our products meet the highest standards for performance and durability. Competitive Pricing: Transparent, budget-friendly pricing helps you optimize your production costs. Once purchased and received by Platinum Tubes, vacuum tubes undergo exacting quality control measures to further assure reliable, sonically acceptable performance. Each power tube is then tested and graded for technical characteristics specified by platinum tubes engineers. Only after a tube successfully passes these exacting challenges is it labeled and put into stock to be sold. Tubes not meeting these criteria are rejected to the supplier or disposed of. Average tube life will depend on several parameters: product type, how the product is installed, loudspeaker efficiency, room size and acoustic damping, listening habits or average sound pressure levels, A.C. line stability and purity, and other circumstances. Generally, preamplifier tubes last up to 5,000 hours, while power amplifier output tubes will last up to 3,000 hours. Near the end of their useful sonic life, aging vacuum tubes may degrade the sonic character of the product(s) they are used in. The sound may become somewhat dry and lifeless, with a noticeable decrease in harmonic richness or bloom. Bass response may be diminished, and musical dynamics may flatten out or compress. Toward the very end of their service life, tubes may become noisy, noticeable as a slight rushing sound or rustling noise. It is far better to replace vacuum tubes prior to the end of their service life, before severe sonic degradation or outright failure occurs. Running vacuum tubes into failure may damage to other internal components and cause needless repair expense. Factors which can shorten tube life include inadequate ventilation, overdriving loudspeakers at continuously high volume levels, severely fluctuating A.C. line conditions (e.g. sagging line voltage during summer peaks of air-conditioning demand), or severe interference pulses or electromagnetic interference. *In the event of a failure, tube(s) must be sent back to us at the buyer’s expense. We will expedite any replacements after testing the tube internally at our expense.
