Had some stuff laying around, and finally picked up 2 switches. 3 inputs and 3 outputs, with Leds to tell me which I selected. It uses a 9 volt battery (slide out tray) to power the leds. Made a little mistake of using 10000mcd leds though, too bright. Gotta fix that sometime, this is quite annoying. Anyways, handy little bugger it is.
Nice, simple, functional, and shiny! Excellent switch man, how much did it cost to make?

Thanks.
All in all 50 something. However, I made a little mistake and ordered the wrong switches first time round, so eventually a bit more than that.

You got a diagram for this or is it a simple pass through switch? 3 different inputs can be outputted to three different outputs depending on what switch is where?
I've been meaingin to make one of these for a while. I love the look of this one. that'll look damn sexy on my desk.
Cheers

There are 2 switches, one which chooses the inputs and the other the outputs. They are simple pass trough switches, it's a 4x3 switch. 4 channels, 3 choices. Respectively for Right channel, Left, ground, and the leds.

At times I'm unfaithful to headphones amps and go see their older sisters
Bad pics (but light!) for a surprisingly good little amp.
It is a "symasym", as per this website : http://www.lf-pro.net/mbittner/Sym5_...ymasym5_3.html . Mine uses a +/-29VDC supply, so it's around 50W into 8ohms. There's a simple preamp integrated (a pair of opa2132 in unity gains serving as buffers for the balance/volume controls). Total cost around 200 in parts (the case was cheap and didn't use a lot of exotic parts, except for two alps pots).
Extremely "clean" sound. It's fast and dynamic, not a lot of euphony to find in it (which is good because the wharfie 8.1 I'm using have enough of it). I'll need more time to evaluate it, but it beats the usual entry level amps with utter ease (nad 320bee, cambridge A300 and the like). PMA made a detailled review of it : http://web.telecom.cz/macura/review.htm
It doesn't have a proper brand name, I ordered it from www.conrad.com. It's order number is 522945 - 8A (site doesn't allow deeplinking to content). It's a well built case, fairly heavy but easy to work on. Has a sloth for euro-type pcb cards. Should be good for a medium sized amp aswell.
In my ever growing effort to get crap done before the national meet I decided that I'd build a switch box tonight so that my one, decent, source could feed the three amps that I want to feed with it. Total build time was between 2 and 3 hours, I stopped several times to eat, drink and be merry. The results - a switch box with a single input and three outputs controlled by a rotary switch which points to each output as it cycles through them.
Tested it tonight briefly and it works like a charm!

Nate,
I'm looking to build a few different selector boxes to do some amp testing, and I was wondering what RCA jacks you used on yours. Thanks

Edit: Also, did you tie together the grounds or use a 3p switch?
