Item is a Polk Audio PSW202 powered subwoofer.
Blows 2A fuse immediately.
There are 2 4700uF / 35v caps in the power supply. Tops are obviously not blown and spewing goo, but the PCB is covered in black goop (like guitar pedal makers use to coat components and "protect" their design).
So. If I cannot see any obvious sign of damage, I "should" be able to set my VOM to resistance and if I touch + and - leads and get a low resistance (40ohm or under) show it bad, right?
Can I do that in circuit usually, or do I need to desolder to test it?
Thanks
Tim
