Service notes: In the switch matrix at column 6 (J206-6, U20-13) and row 3 (J208-3, U18-5). Gap 1/16 inch; clean by pulling card stock through the closed contacts, never a file. One switch that fails T.1 is its gap, the wire at the lug or its diode; a shorted diode makes the whole column or row misread. A whole column dead is U20 or the J206 pin, a whole row is the row comparator. A3 Switches and optos
