6SN7 Homebrew Preamp
OK, don't laugh, but not only does this look cool, but sounds quite nice too. Its a wooden Salad bowl from Crate and Barrel that I made into a preamp.
A pair of 6SN7 Tubes, and a nice Hammond power Tranny. Also has LED Bais. The pre comes with both a 6X5 rectifier and a plug in SS rectifier (FWBR 1N4007 x 4), so you can decide which is best. Has DC on heaters. The B+ is around 275V and it is a simple plate / cathode follower circuit. Nice caps too. The bottom is open, so caution around kids / animals. How's $275? I actually have another identical wooden bowl that matches the pre available too for a matching amp...These would look pretty cool next to one of those IKEA wooden Salad Bowl Speakers...

No, I bought two of them from a local Crate and Barrel outlet store...they had tons of them,
But a few months later they were all gone. I used to stop in every few months to see if they had any more - but they were always out. I check on fleabay every now and then...nada... Too bad, these worked perfectly...

Oh, the tubes - two Tung Sol "Mouse Ears" 6SN7-GT, and an RCA 6X5-GT...

Great looking preamp!
 But I'm confused - what's the octal base with the pins up? EDIT: Doh! The SS rectifier.
