I got a kl503 I was talking to my wife at work when she reported to me my power dropped off .. so I stopped transmitting and when I got home that day I seen this..
It has at first glance has a bad ceramic cap. I was going to go through it and replace all the similar ceramic caps.. the cap has "104" on it so it is 0.10 uF but I don't know the voltage "50 volts?"
When I replace them I want to double the voltage so this won't happen again..

now I know this amp is a cheep amp but there is no reason I cant make it more durable.. :blink:

here is a pic if it helps to guess what the voltage of the carp are...?
as you can see the ceramic cap is split..

 

well I think there 50V caps so I found some 100v caps I have not ordered them yet.. it turns out it was my Wilson 1000 coax got pinched in a door of my wife's car... and may have done this...

the cap that blow out is C7 so I ripped out C7, C6, C5, C4 and will be replacing them with higher quality caps

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
