[Elecraft] Problem with Current Meter

[Eduardo Jacob]

Hi

A friend of mine is having problems with the current detector. When he
presses the display button the voltage is displayed but the current shows 0.
We have been tracing the circuit which is fairly straight and we are not
able to get the solution. We have changed the LM833 and the PN2222A
transistor. We have checked the current sense resistor and it seems it's
working. Does any body found before this problem?
