![Weston Acoustics granite 6SN7 preamp](http://musicalita.com/files/2010/10/Weston-Acoustics-granite-preamp.jpg)
I was gob-smacked when I saw these last weekend. The latest creation from Earle Weston of Weston Acoustics. The monoblacks are 300B, the preamp uses a 6SN7 per channel. They sounded very nice driving a small pair of 3″ fullrange drivers in a transmission line type of cabinet.
