not really an amp. but here's a Luxman input selector switch that i converted to a Passive preamp by adding a 50k blue velvet.
An externally hosted image should be here but it was not working when we last tested it.

TDA7294 Amp build
Here is my latest build. Based off of this thread, TDA7294 + Power Transistors AMP (TDA7293 to come also). The case was made for a preamp type circuit, I had to add the binding posts on the back and was a little tight on the inside. I'm waiting on parts to add an headphone out to the front 1/4" jack. The case came with the front knob, 1/4" jack, IEC and toggle switch. Sound is clean and powerful. On to the next.

I suppose I'll add my integrated amp to the listing.
