The DIY LA2A PCB and parts kit is a great project for anyone interested in doing an easy project while getting an introduction to tube circuitry. This project is a compact PCB with a low component count. All tube wiring is done on the PCB meaning lower noise and less time building your unit. The calibration process is a painless process, simply adjusting one trim pot on the main board.


This PCB +kit pairs perfectly with the HVPSU or Heater Regulator kit for efficient clean DC voltage.


  • Lundahl input and output transformer footprints on PCB.
  • Original 12AX7, 12BH7 and 6AQ5 tubes configuration.
