Quad 303, completely rebuilt, everything new south of the rectifier:
- PSU capacitors
- All components on the PCB: all resistors, capacitors, and inductors
- All five power transistors
This 303 is tested and aligned at five points and warranted (new parts & labour) for 12 months from date of purchase. It comfortably exceeds all factory specifications, and will be 'good to go' for at least 28,000 hours of use based on component manufacturer specifications.
