Audio Cabinet

IMG_20161119_132910.jpg

I planned to build a record cabinet to house a new turntable I purchased. I wanted to use mostly recycled wood and scrap laying around the shop. Other than fabric this was more than achievable. Free material from craigslist was also useful for this project.

Inspiration

The project was partially inspired by a "Sunday Project' I did previously. I disassembled an old record cabinet and converted it into a portable audio chest.

Refashion

The original turntable purchased for this cabinet had a poorly machined platter and was returned. I picked up an old replacement turntable from an estate sale and restored it. The instructable for this project is at the link below. Because the size of the new turntable was slightly larger I modified the cabinet top to accommodate it.

The equalizer was chosen to act as an intermediary between a smartphone or computer and the receiver. A 3.5 aux to RCA cable goes to the input and the output is RCA to receiver. The receiver didn't have an Auxillary input so I just ran to the CD function. Wire up the speakers, receiver antennae and turntable. You can also run a TV into the unit.

AUX/Bluetooth
