Not my finest breadboard work, but it turned out ok...
(power supply not installed yet, but it's just a simple TLE rail splitter with a couple caps.
Yeah I know, some of those are pretty ugly joints. I went back and touched up most of them after the pic (as well as did a few that I missed the first time) and trimmed off those excess leads
(the intended board layout was cleaner with everything running vertical or horizontal, but I goofed up midway and wound up jiggering things on the fly
This was a nutty headphone amp project that I cooked up to mimic Jan Meier's "active balanced ground" topology: http://www.meier-audio.homepage.t-online.de/grounds.htm
Three dual opamps were used. The first as an input buffer and where the bass boost switch is located. The other two for the output channels.I think I managed to squeeze in a gain switch somewhere in there too. My mistake, it was a switch for an output pad resistor.

Adam,
I have never been so drunk that I drank from the urinal. Those hockey pucks in them would get in your way anyway.

Ok, I'll post a random one:
I recently started a little bizarre, but healthy and harmless hobby: collecting driftwood for sculptures. Right now I'm hoping to make a large sculpture of an Orca whale probably for the backyard of our shop. Have collected the head, dorsal fin, tail, and some of the most important pieces to round out the body. Now needing to find pectoral fins, extra filler pieces, and some novel way of attaching it all together and elevating it off the ground. Debating whether I am up to the challenge to make this 10-12 ft. long scultpture "breach" or not.
Oh, the odd things we do to stay in shape
Cheers,
Clark
In other news, am making good headway on a new large bookshelf model to release soonish. Taking sea related name suggestions.

It has tempted me more than once to use a piece of driftwood somehow in a speaker design. Non conventional is great in trade for boxes, boxes, and more box-shaped pieces of audio gear.

Back to bread boarding. Has anyone else made their own phenolic eyelet board for use in a hifi? I have made a few for guitar amps and always thought it would make a nice clean build that would be easy to maintain.
