    Hello i have a Yamaha PC2002M
    and i am getting mixted advice on this part:confused:
    its marked with the number 100 with a lighting bolt
    i will enclose a picture
    on the Scamatic its marked as a Resistor
    but on the front of the PCB it has a mark
    a letter P in a circle like this P10 ?

    Now Yamaha says its a fuse resistor 100Ω 1/4W
    but i seen micron fuse resistors 10 Ω 0.16A
    so if anyone has seen this part and knows what it is
    i be very Happy for your Help !! :D

    Thank you
    Robert

    Seems more like capacitors to me but I could be wrong as I have never came across those.

    Could be fusible R's too.

    Can you provide a picture of where they were soldered as the symbols marked on the PCB will be helpful.

    Have you tried some simple tests like resistance, capacitance, weight etc?

    Hello yes on the ohms its meaures 10ohmd
    and if i use a Capastior meter it shows 100
    i also belive its a fuse resistor

    Do you mean:
    Resistance measured 10 Ohms?
    Capacitance measured 100 Farads?

    Did you measure at what current the fuse will blow?

    Are you getting 10Ω when measured with Analog meter or Digital Meter ?

    If all shows the exact reading then it is a 10Ω resistor

    Hello here is the board with the P10
    in a Circle

    on another amp the litte blue Fuser are '
    replaced with a micron 78 0.16ma fuser resisitors
