The Sovtek 5Y3GT is an indirectly heated, full-wave rectifier vacuum tube manufactured in Russia for use in guitar amplifiers and general-purpose audio equipment. [1, 2, 3]
Key Characteristics & Specifications
Tube Type: Indirectly heated full-wave rectifier diode [1, 2]
Filament Voltage: 5 V [1]
Filament Current: 2 A (± 0.2 A) [1]
Maximum Output: 140 mA [1]
Country of Origin: Russia [1, 2]
Compatibility: Can substitute for 5Y3, 5Y3G, 5Y3GA, 5Y3GTA, 5Y3GTB, R52, and U50. [1, 2]
Performance & Tone Notes
Indirect Heating Design: Unlike traditional directly heated vintage 5Y3 tubes, the Sovtek variant is indirectly heated, which provides a slower warm-up ("slow turn-on") that helps extend the lifespan of power output tubes. [1]
Voltage Drop Behavior: Some vintage amp purists note that the Sovtek 5Y3GT has a lower voltage drop than original NOS (New Old Stock) tubes like RCA units, resulting in higher plate voltages and a slightly stiffer or cleaner feel rather than the deep, loose sag of a traditional direct-heated 5Y3. [1, 2]
Common Applications: Frequently utilized in lower-wattage or vintage-style tube amplifiers (such as smaller Fender or boutique circuits) to convert AC power into DC voltage. [1, 2, 3]
