Please can you tell me what are the valuer of the Resistor and Capacitor resonnator value of the HP 11C calculator.
The capacitor is broken on mine and would like to solder a new one but I dont know the value. The resistor value is for my confirmation of what I mesured

It's an LC (Inductor/Capacitor) circuit, not RC. The values I have (found in both a 12C and a 16C, I guess the 11C is the same) are 180uH for the inductor and 180pF for the capacitor.
