Ok kids, time to show off your stuff.

Things of DIY nature that you have built recently from scratch are most welcome! This is not a cosmetic/beauty contest so don't be shy ;)

Sir Arnold,

Are these limited to DIY amps? My DIY are mostly speakers and interconnects.

By the way, how do I post in the Photo Gallery?

Here are some of what I've done recently...

Equipment Rack of my own design. Each part has been isolated either by tips, cones, isolation platforms.

Here's the original thread on the construction process:
Moz's Rack

Here are some pics of the prototype after assembly. Also shown is the tube-rectified DIY preamp, IC & the great sounding Rega Planet courtesy of Hyperion. Call him a try it out for yourself.

Assembling & levelling:
Image

Before finalizing the setup & fixing the wires. Ongoing are DIY power cords & extension power bars after replacing the wall outlet with hospital-grade sockets:
Image

In the corner when speakers are parked:

Closeup of sand-filled posts with cap off:

Post-shelf shot. Note sand-filled isolation platform on "tips" The power amp is also on brass cones on top of a similar isolation platform.

Rack version 2 will have spring-suspended shelves.

Mickey's new baby - a "50" power amplifier!

Congratulations! I know you will not post it so i did it for you ;)

Image

BTW, if "50" tubes have dwindled in numbers, it's because of Mickey ;)
