摘要：
An electronic tuning block including a plurality of screw drive type variable resistors are juxtaposed parallel to one another obliquely on an insulating substrate, and holes for receiving pointers fitted to the screws of the variable resistors and holes for receiving rotary knobs fitted to the tips of the screw shaft are formed on the upper surface of a box-shaped insulating case which is fixed to the insulating substrate.
