The BuffTest is an extremely accurate (within 0.03% error) buffered mult with a clever little circuit that lets you turn it into a cable tester at the push of a button. It can also be patched as 3x manual gates and, if you can find a use for it, 3x negative gates. Bi-colour LEDs indicate voltage. The BuffTest has reverse voltage protection.
Front panel is PCB material with black soldermask and ENIG gold lettering. Secondary labelling is printed in the copper under the soldermask for an embossed look. Also lightning bolts.
