Hoping good ol Ken will see this

I believe the monitor in my Double Dragon cab is a WG K7000 (anyone familiar with what monitors are generally in these cabs?). There is no label anywhere for me to go by but the picture from bobs site looks like it.
I was looking at the pcb and noticed that 3 of the capacitors have some kind of glop around the bottom edge of them. Are these capacitors leaking?
So I'm pretty sure I need to order a cap kit from bob, and practice my soldering skills.
Discharging the monitor sounds pretty simple, but still is a bit scary.
Wish me luck.
