Very good upgrades for your 148 or 2000 GTL

Clarifier mod for Teaberry Stalker XV & XX (15 & 20).
This mod increases slide and corrects the center slot issue common with
these boards. Could be used in the 142 GTL and Washington with some
changes as well. You will need a dead 148 or 2000 GTL for a few parts.
This mod has been tested and does what it says if done properly. It will
give you almost 10kc slide over the typical 3 kc modification.

Convert a 3 position rotary switch to 5 or 6 positions.
