Rack mount power amplifier 1.

Another idiotic (never finished???) idea of mine.

As I go back to build audio equipment and bought enormous amount of old audio gear, I eagerly need something to test it in my lab. I started to build my test equipment into 19" racks (than disassembled everything. 😂)

For testing, I need a set of speakers, and a power amplifier.

Requirements:

• Built into a 1U rackmount enclosure (I hate things on trays in the rack)
• Use modul parts: Switching PSU, Class D amplifier board
• Put all of the connectors to the front, to be easily accessible
• Optional: back connectors with front/back switch

Ordered:

• 500VA 24V PSU - $16.45
• TPA3116 120W Class D board - $10.71
• 1U Rack Chassis - $44.82 + $56.73 (Shipping)

Whaaaaat?????

No way.

Once more:

• 500VA 24V PSU - $16.45
• TPA3116 120W Class D board - $10.71
• 1U Rack Chassis - $44.82 + $56.73 (Shipping)

Think a bit, look around.

Buy the chassis locally

• 1U Rack Chassis - $50

Whaaaaat?????

No way.

Next iteration:

• 500VA 24V PSU - $16.45
• TPA3116 120W Class D board - $10.71
• 1U Rack Chassis - $50

Look around more thoroughly:

I found quite a few outdated or broken 1U network switches. $12-$15 each

Much better.

The things arriving:

The Amp:

The PSU:

The Switch for repurpose:

My new A3 printer and sheet laminator is on the way to me. So the plan is to throw away the parts from one of the switches. build the connectors, volume pot on the front of the switch chassis or add some holding consoles (probably 3D printed) and design a new front panel, print laminate, cut and finally glue it with a double sided adhesive tape.

This is the plan. Looks super fast to me. Hopefully not another half baked, shelved project.
