5X9 Tubes

1. 9 Pin Miniature Base – This type of base is commonly used in high frequency applications such as radio, television and audio amplifiers, usually for 9-pin dual triode tubes. It is an industry standard for tubes such as the 6L6, the 6V6 and the EL34. 2. 9 Pin Compactron Base – This is an industrial standard for 9-pin dual triode tubes. It is a common type of base used in television and stereo amplifiers. 3. 9 Pin Octal Base – This base is commonly used in high-power audio amplifiers, most notably the 6L6 and the EL34. It offers higher voltage operation compared to other 9-pin tubes. 4. 9 Pin SOD-123 – This type of base is a common choice for miniature 9-pin tubes used in various electronic circuits. It offers a more compact design compared to the other types. 5. 9 Pin Noval Base – This is a less common 9-pin base commonly found on tubes such as the 6BM8, the 6AQ5, the 6AQ8 and the 6AQ10. It is common in audio amplifiers and television circuits.
