Features:
This product employs the original 6J1 tube for optimal performance. Its main filter capacitor is an imported 1000UF/25V, and the coupling capacitor is 1UF, ensuring high-quality capacitation. Resistance is handled by a five-ring 1% metal resistance, contributing to a good signal-to-noise ratio for the device.
The product’s PCB makes use of a 1.6mm thick double-sided board, 2.0 oz copper thickness, and full tinning process to maintain good passing performance of large and small currents. Our PCB quality is first-class. The input and output incorporate a gold-plated RCA seat, offering both durability and aesthetic appeal.
The board boasts a reasonable, well-arranged wiring system, is visually appealing and produces low current noise. This product requires a DC12 V2A Power Supply (not included). Its net weight is 0.4KG and its dimensions are 137mm length, 104mm width, and 41mm height (excluding tube height).
Important Tips:
Take note that this finished machine is a pre-amplifier and not a power amplifier, so it should be used with a post-amp or active speaker. Do not connect directly to passive speakers, speakers, or earphones as power amplifiers. It is not suitable for use in vehicles due to unstable voltage conditions.
Low-quality audio cables or power supplies may cause noise current sound. We recommend the use of high-quality audio cables or power supplies for the best performance. Ensure your sound source is of good quality since the preamplifier’s function is to amplify the sound source. If your sound source is of poor quality, the preamplifier will amplify the noise instead of the music.
Before using, confirm whether the electron tube is properly inserted into the base. Make sure to do this while the power is off.
Package includes one pre-amplifier (Power supply not included).
