About the Tube Cad Journal Aikido 9-pin
The Tube Cad Journal Aikido 9-pin PCB is a robust printed circuit board made in the USA, featuring extra thick 0.094 inch FR-4 material, double-sided with plated-through 2oz copper traces. It measures 4 by 10 inches and includes eight mounting holes to prevent bending during tube insertion and removal. Each PCB supports two Aikido line-stage amplifiers, allowing for stereo unbalanced use or one channel of balanced amplification. The design supports various 9-pin triode tubes, with detailed tube gain and operating parameters provided for optimal customization. The PCB is intended for use with high-voltage power supplies and requires careful handling due to shock hazards. This product is favored for its durability, flexibility in tube choice, and suitability for audiophile-grade tube preamplifier projects.
