Ugly prototype contest

[SY]

I was amused to see some good-natured jibes in Phred's direction in another thread; the subject was a prototype that he made. Particularly amusing to me, since if that's his worst, it's better than my best. Compound that with EC daring me to show my work, and it can mean only one thing: ugly prototype contest!

Now, I have to admit that I'm terribly impressed with the quality and appearance of so much of the work shown here by the members. A lot of it is real audio eye-candy, masterpieces of design and execution. I'm in awe of the guys who can pull that off. This contest is for the rest of us.

My first entry dates from a few days ago, during a discussion of the influence of an input tube's cathode source impedance on feedback ratios. It's the Mullard input stage, executed as only a real artist like me can:

My second entry, looking at the effect (or lack thereof) of operating points and mu on constant-current diff amps. It's what prompted EC's dare. Here ya go, buddy!

 

[Vivek]

Really ugly but nice. 😀

 

[UrSv]

Very neat. I especially like the star ground and separation of signal and supply...

 

[Bricolo]

My gainclone prototype

You guys are not going to

believe this but I would put you all to shame!

my prototypes are truly worse. They are that bad that my wife hides the camera when i am working on one!

Though I built my first/prototype IGC straight into a rather small, scruffy box, it was a real pain if any components needed changing (which they frequently did) hence the 'rat's nest'...

It sounded pretty good though.

I think Ropie wins the medal on this contest😱

Here's mine

This was for a variable power supply for testing my first amp. Sadly, I still haven't finished the real box. . .

An externally hosted image should be here but it was not working when we last tested it.

oooohhhh something I can participate in

My very first mic preamp/mixer 🙂 No longer functional, as some wires fell off 😉 (made in '89 to mix voice with music for a radio play for uni!).....

[Magura]

I see we have a new CLEAR no. one 😀

Well, Sandy's is my fave so far. The use of a Coke box is very southern. Had you thought about putting the box up on some cinderblocks?

This is all very theraputic to me.

Thanks Joe, I think Bricolo's has a certain "safety first" charm to it (ie, the risk of being trodden on or swept up whilst on 😀 )

 

[Netlist]

This reminds me of an old thread.
I did nothing special to make it ugly, it just happened.. 😉

Is the contest still open? One channel of ZenV4.

Ratnest:😀

 

[Ropie]

I think it's quite stylish Hugo, reminds me of some architectural concept models from colege 😉

 

[JOE DIRT®]

LMAO!!!....this gets better and better!!.....I think I`m gonna have to dig up something now to show.......I think Netlist should get the medal now!!..hahahaha

I dont know if Netlist's project qualifies, the capacitor wiring is way too neat. Now if he hadnt used the crimp connectors...

The copper is cool.

I love the window reflection.
