Bottlehead BeePre 300B Preamp
$1200 New. This is the basic kit without the BeeQuiet Attenuater. http://bottlehead.com/beepre-300b-preamplifier-kit-specs/
I built this last year. Used it for 2 months then moved on to a Passive Solid State Attenuater. It's been in storage for the last year.
It works well. Cosmetically, the covers of the transformers have collected some tarnish and discoloration.
Two EL84 and two 300B tubes that shipped with the kit. The tubes probably have about 40 hours on them.
I'll cover shipping costs
