6J3 Tube Pre-amplifier
Custom circuit design
Custom circuit design of the base, original 6J1 tube pre-amp. Software based signal analysis of the 6J1 generated some key characteristics that required tuning. The 6J3 tubes, audiophile quality capacitors, circuit configuration, VU meter, and Bluetooth connectivity are all upgrades to the original base design.
Date
January 2023
Used a software based signal analysis suite to find characteristics which were unacceptable. Upgraded ALL components except the transistors. Audiophile quality capacitors, 6J3 tubes. Added a VU meter, and a Bluetooth connectivity module.
