Step-by-Step Tutorial: Building a Gibson GA1-RVT Clone Amp with Reverb and Tremolo
Part 1: Chassis Preparation
-
Prepare the Chassis Layout:
- Based on the components needed, mark and measure the positions for the tubes, transformers, switches, controls, pots, and other parts on the chassis.
- Ensure proper spacing for cooling and accessibility of components.
-
Machining the Chassis:
- Drill pilot holes for each component's position on the chassis.
- Use a step bit to gradually enlarge the holes to the required diameters.
- Smooth out any sharp edges or burrs using sandpaper.
-
Drill Screw Holes for Tube Bases:
- Drill holes for securing the tube bases onto the chassis.
- Ensure precise alignment and spacing for a neat arrangement.
-
Cut Out Openings for Transformers:
- Determine the location for the power transformer and output transformer.
- Cut out appropriate openings on the chassis for mounting the transformers securely.
-
Prepare Control Panel Layout:
- Design and mark the layout for the control panel including input jacks, potentiometers, toggle switch, and other controls.
- Drill holes for each component on the control panel.
-
Finalize Chassis Preparation:
- Check all holes for alignment and clearance.
- Drill holes for securing the chassis to the cabinet once it arrives.
- Ensure all components fit properly and are ready for assembly.
-
Consider Painting the Chassis:
- Decide on a suitable color for painting the chassis.
- Plan for painting after the chassis is installed in the cabinet to prevent damage.
-
Wrap Up Part 1:
- Review the completed chassis preparation tasks.
- Prepare for the arrival of the cabinet and subsequent assembly in Part 2 of the project.
By following these steps, you will have successfully prepared the chassis for the Gibson GA1-RVT clone amp, setting the stage for the next phase of the build process. Stay tuned for Part 2 for cabinet evaluation, painting, assembly, and wiring.
