Applications
Audio Amplifiers: The 6Z4 is used in guitar amplifiers, hi-fi preamps, and small power amplifiers. For example, it is featured in the Aktiv Audio 5-watt Class A tube amplifier, paired with a Ruby Tubes 12AX7AC5HG preamp tube and a 6V6GTSTR power tube, delivering clean to distorted tones.
Digital-to-Analog Converters (DACs): Found in devices like the Line Magnetic LM-502CA DAC, where it works alongside 12AU7 tubes in the output stage to provide a warm, tube-driven sound.
DIY Projects: Suitable for dual-mono preamp designs or other low-current applications (up to 70mA), often paired with chokes for improved voltage regulation.
Amplifiers Using the 6Z4 Tube (B7A 7-Pin Base)
Identifying specific amplifiers that use the 6Z4 (B7A 7-pin base) is challenging due to limited documentation in English-language sources and the tube’s niche use in certain markets (e.g., Chinese hi-fi and DIY audio). However, based on available information and the tube’s application in rectifier circuits, here are the types of amplifiers and specific examples where the 6Z4 (B7A) is likely used:
1. Chinese Hi-Fi Amplifiers:
• The 6Z4 (B7A) is frequently used in Chinese-made vacuum tube amplifiers, especially in the power supply section of single-ended triode (SET) or push-pull amplifiers. These amplifiers often target the audiophile market and use tubes like 6N1, 6N2, EL34, or 6P3P for amplification.
• Example: Generic Chinese single-ended stereo power amplifiers (e.g., 6P1, 6P14, or 6P3P-based designs) often incorporate a 6Z4 rectifier tube in their power supply. A specific product mentioned is the LG239B 6Z4×2 parallel bile rectifier filter board, designed for 6P1/6P14/6P3P single-ended stereo amplifiers, with an output current up to 150mA.
• Brands like Yaqin, OldChen, or Muzishare (common in Chinese hi-fi) may use the 6Z4 in some models, particularly budget or mid-range tube amps, though exact model numbers are rarely specified in documentation.
2. DIY and Custom Amplifiers:
• The 6Z4 (B7A) is popular in DIY audio communities, especially for building or modifying small vintage-style amplifiers. It’s used in power supply circuits for amps like the Fender Tweed Champ (5F1) or Tweed Deluxe (5E3) clones, where a rectifier tube is needed to provide the “sag” and soft-start characteristics valued in guitar amps.
• The 6Z4’s ability to handle up to 150mA DC output makes it suitable for low-to-medium power amplifiers, often paired with tubes like 6V6, EL84, or 6BQ5 in DIY projects.
• Forums like diyAudio suggest that 7-pin rectifier tubes like the 6X4 (a related tube) are used in all-7-pin amplifier designs, and the 6Z4 (B7A) could be substituted in similar circuits due to its compatible base and rectifier function.
