The Tung-Sol 6SL7 (often seen as the 6SL7GT or Gold Pin reissue) is a high-gain dual triode vacuum tube widely used in the pre-amplification stages of vintage and modern hi-fi audio equipment and classic guitar/bass amplifiers (such as vintage Ampeg models). [1, 2, 3, 4, 5]
Key Characteristics & Specifications
Tube Type: Twin/dual triode voltage amplifier (8-pin octal base) [1, 2, 3]
Amplification Factor (μ / Gain): 70 [1, 2]
Heater Voltage / Current: 6.3 V at 300 mA [1, 2]
Max Plate Voltage: 300 V (250 V typical) [1, 2]
Plate Dissipation: 1 W per triode [1, 2]
Current Production vs. NOS (New Old Stock)
Current Production: Modern Tung-Sol 6SL7GT tubes (and their Gold Pin variants) are manufactured in Russia at the Reflektor (Xpo-Pul) factory under New Sensor Corporation. Users on forums like AudioKarma note that the Gold Pin reissues offer a smooth, clean sound with low noise, making them a popular and reliable drop-in upgrade compared to stock Chinese tubes. [1, 2, 3]
Vintage / Military Equivalents (NOS): Original vintage Tung-Sol production and specialized military/industrial variants—such as the 6188 (milspec/industrial) and the revered black-glass 6SU7GTY ("Super 6SL7")—are rare, factory-balanced collector items known for heavy-duty top-mica vibration dampening and exceptional linearity. Opinions on platforms like TalkBass reflect mixed views: some audiophiles prefer the fatter, rounder tone of true NOS tubes, while others favor current-production Tung-Sol reissues for everyday reliability and lower microphonics risk. [1, 2, 3, 4]
