    A little dangerous to apply just ANY voltage to the circuit.

    You could start by applying 1.5V, then 3.3V then maybe higher to the trace where the output of the LDO is supposed to be.

    Before buying a component that may or may not work or even damage the rest of the circuit.

    I was thinking the same.

    If it's in series with the rest of the circuit and the input voltage can vary it's quite likely though that it's a fixed voltage regulator...

    One would need to draw part of the circuit.

    Hello Pwdixon,
    i think it must be some voltage regulator, the pinning of the HT1015-1 fits, the homepage says this is for battery devices with very low current consumption.
    I also think the output of 1.5 volt is not too much to operate 2 oscillation circuits .
    So i just can hope the output is right - not too low and not too much.
    Now i need to try to get an sample of the part ...Taiwan producer..hmm....
    We´ll see.

    I see the other post now.... I will try to operate open with an external power supply with 1.5 volt DC.
    Hope nothing will happen if I operat without the silver iron cover that was mounted over the small PCB of the oszillation unit.
    Thanks again

    Op amps also have 5 pins such as that. So do lots of other chips.

    Is there another similar part on the board?
