Custom made by order tube pre-amplifier. Many people are asking if I made a tube pre-amplifier with reasonable price without burning their wallet. The answer is yes. I can do tube pre-amplifier based on your order. This pre-amplifier use 3 pieces of 12AX7 (high-mu preamp tubes) which commonly used by many amplifier design. The circuit is a clone of Marantz 7 pre-amplifier. Power transformer is 80 VA (76*40 core) with 6z5p tube rectifier. Voltage amplifier gain is 15x (max. 12 Volt p-p). Sufficient to drive any power amplifier from various source. Take note that current CD Player / DAC output is 2V p-p. Production time is up to 3 weeks as the chassis must be imported from overseas while other components can be sourced locally or online (Mouser / Digikey / RS Components). Price starts from SGD 250.00 and it comes with Shuguang tubes. Please feel free to PM me to discuss. No obligation and fee for discussion.
