Hi Excitable,
There should be replacement caps available from Mouser or Digikey that will fit the bill.

This is a 0.1uF/100V film cap.. To find an exact fit measure the lead spacing and diameter as well.

I do need to mention that this cap may have failed because it was defective, underspecified or overstressed due to some other component failure.

Can you provide more detail as to what point in the circuit this part was removed from? If for example it was removed from the zobel network in the output of an amplifier its failure could be an indication of either oscillation in the power amplifier or high levels of ultrasonic content in the signal driving it.

i dont know as to what point in the amp it was removed.
the other cap that died was a 47 uF 100v
the amp had a bad hum and was looking at it to try to figure out what was making it do that ..ran across these 2 near each other that leaked all over the board.
i cleaned up the pcb to make it easier to see the leads and where they go.
all i know is its the amp..other then that i am lost.

I see some bad things here, clearly someone has been in here doing bad repairs. I recommend you seek out a qualified service tech or possibly purchase a replacement amp.

yeah there is some nasty stuff there but if i can mend this one cheap then i want to give it a shot.
also even if it doesn't get any better i cant really make it any worse...lol
