1. Tubes 5V6GT is a dual diode-pentode vacuum tube type developed by Tung-Sol, General Electric, and Philips in the mid-20th century. It consists of an indirectly heated oxide-coated cathode, and two half-wave rectifier diodes, with a common anode plate.
2. The pentode plate is connected to the anode plate, while the diode section is composed of a separate anode and two separate cathodes.
3. The 5V6GT has been used in many types of audio, RF, and IF applications, including in sound reinforcement and recording studio applications.
4. It is a rugged device with a relatively low number of interconnects, making it well-suited for use in portable and battery-operated equipment.
5. The 5V6GT tube has a strong, vibrant character when overdriven, and it has become a favored tube in many guitar amplifiers.
