PL519
Power Pentode for Radiofrequency and HF Linear Amplifiers
High Cathode Current – Maximum Anode Dissipation (Magnoval Equivalent)
ROBUSTNESS AND HIGH RF PERFORMANCE
• IDEAL FOR LINEAR AMPLIFIERS: The valve of choice for repairing or building commercial HF linear amplifiers (e.g., Zetagi BV131, BV135, BV2001 MKII) thanks to its exceptional tolerance to power peaks.
• REINFORCED MAGNOVAL STRUCTURE: An enhanced evolution of the PL509 model, offering greater anode heat dissipation and tolerating very high peak cathode currents.
• TOP ANODE CAP: High-isolation design to safely manage high transient anode voltages.
Thermionic Reliability for Radio Amateurs and Laboratories
The PL519 is an indirectly heated power pentode originally designed for the horizontal deflection stages of color televisions, but which has found its natural field of excellence in the world of radio frequency. Highly appreciated by radio amateurs and repair technicians, this valve guarantees excellent modulation linearity in the citizen's band (CB) and on decametric HF frequencies, offering an unbeatable quality/price ratio in restoring the original power of your vintage or modern equipment and amplifiers.
