Boost

Based on the Dallas Rangemaster with a few mods.  Available in both Silicon and Germanium versions. Very versatile for such a small package with three knobs controlling bass, gain and volume.  Not the cleanest booster but that's not a bad thing.  Runs on a standard 2.1mm boss style 9v power adapter.  Current draw ~1mA. 

$160CAD shipped.
