Deluxe chopstick, made of white plastic with colorful lettering. If using a chopstick as a diagnosis tool then do it in style with this nice work of art. The price is per piece so if you want to work on an amp and have some sushi on the side then you'll need to order two.
Pair of economy chopsticks. Commonly used as a tool to diagnose issues in an amp like finding microphonic tubes while tapping them with the chopstick or carefully wiggling wires to find the source of a crackle. May also be used to eat food.
Quad Tube Amplifier Bias Meter. It measures the cathode current of the power tube for bias reading (at low voltage side of the tubes). Tests EL84, 6BQ5, 6P14 etc. Four bias probes included.
