Hi all i have a pair of mission 731 speakers which the tweeter in one does not work i have continuity through the driver which led me to the xover i have put a photo up ,,
I think the component with 475K 100V written on it is at fault i have removed it and am getting an open circuit reading is this a resistor of some type and any idea here to get one ?

 

this was the photo i meant to put up..

 

Hello,

It is a capacitor of 4.7 μF 100 Volts.

Here is a page from the EDUCYPEDIA on component coding.

There you will find this page with the solution:

A capacitor will check open on a meter. It is a reactive element in the path to your tweeter, and preferentially passes the upper frequencies.

Take power down and short around the capacitor with a clip lead. Turn the amp back on at an audible level and listen to that tweeter. If you hear sound, the cap is bad. If not, it's something else.

 

ok thanks for that will try it ..

 

I have sorted it now it must have been a dodgy connection i soldered it back together and it works fine ..
thanks for your replys ,,
