High gain vacuum tube preamplifier

After nearly two months of designing, prototyping and having pcb made, this project is comming along nicely. This is a vacuum tube preamplifier with three 12AX7 tubes. Preamp Bass Middle Treble Presence Volume controlls. PCB's are made by PCBway and are of great quality! I've inspected all traces and found no mistakes. Since this is a tube preamp it has to withstand 400 volts plus the dissipation of heat from the resistors. After a 24 hour stresstest there was no sign of stress on the PCB! Great prices for even greater products!
