Steampunk Vacuum Tube Amplifier

This is a steampunk style case for the Model 16LS Stereo Integrated Tube Amplifier kit. This project includes some modifications to the kit, including adding the following features: 1. Attenuator instead of the potentiometer for volume control - removing the scratchiest when adjusting volume, but also increasing the useful low volume range. I had a bad hum which was fixed by replacing this component too. 2. Optional - Right / Left balance attenuator (I have not yet implemented this, at the moment it just holds the right knob in place) 3. Stereo VU Meter, this lets you adjust the volume of the source system to the appropriate line level and amplify the signal through the vacuum tubes. 4. Automatic On/Off when music is playing (I often forget to turn off the amp when not in use). This is accomplished through a SparkFun Audio Shield, Arduino Uno, and a Solid State Relay. 5. Add C14 plug at the back of the unit with integrated On/Off switch and Fuse 6. Programmable button at back of unit - sends commands to Arduino for features such as manual On/Off. 7. External speaker jacks at back - instead of the goofy on-board vertical jacks. 8. External RCA input jacks at back - instead of the goofy front facing jacks. 9. Input selection switch to select between Bluetooth Input vs RCA jacks. (Note: I believe the audio quality is typically better via RCA direct from a quality source, vs Bluetooth) The bottom of the case is made from 6mm thick MDF The top of the case around the tubes is made from 3.2mm Glass (though you could use a different heat resistant material such as aluminum, copper sheet provided you keep it away from the electrical contacts, the thickness is not overly important) The case body, and knobs are made from 3D printed PLA, epoxied together, sanded, putty and painted such that the joints are no longer visible. Extra texture and contrast is provided by aging the copper through painting techniques, and stainless steel screws
