Description: 108Platinum Tubes Penta Laboratories 3CX2500F3 Ceramic/Metal Medium-Mu Power Triode Normal 0 false false false EN-US X-NONE X-NONE The Penta Laboratories 3CX2500F3/PL8251/YU108 is a medium-mu metal/ceramic external anode power triode. Maximum plate dissipation for this tube is 4000 watts, and cooling is forced air. At moderate voltages, relatively high-power output can be obtained from the PL8251/3CX2500F3/YU108 as an amplifier, oscillator, or modulator. For grounded-grid operation, excellent shielding between the input and output circuits is provided by the grid, conveniently terminated between the filament and plate terminals. The PL8251/3CX2500F3/YU108 is designed using a rugged, low-inductance cylindrical filament stem, making it especially well-suited for use in the linear filament tank circuit under VHF operation. The flexible base leads for filament connection serve to simplify socketing in low-frequency applications, and the rugged grid flange is ideal for mounting under industrial conditions.

Deep Expertise: We understand the unique demands of RF heat sealing technology and offer a comprehensive selection of parts for top brands. Quality Assurance: Our replacement RF power oscillator tubes, rotary RF welding parts, RF amplifier components, diodes, and capacitors meet the highest standards for performance and durability. Top Choice for Repairs: Leading RF welding repair experts trust Penta Labs for OEM-equivalent replacement tubes in some of the world's most demanding heat-sealing applications. 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.
