Boss Super Chorus

[pedalman]

A friend of mine broke his Super Chorus and gave it to me to fix.
He said it was working fine till he plugged in the 9v jack.
First place i should look is the cap at the 9v right ?
How would a bad cap read ?

If I were you I'd check the conection of the 9V jack to the board first. I've seen those joints come loose from usage and managed to repair a 'broken' VS H2O Chorus that way

The first step is determining as much as you can about exactly what happened when it failed.  Which power supply?  Did he hear or smell anything, did it get hot? etc.  That might give you more clues as to what to look for.

Usually always something simple

yeah, i would guess the plug took a bump, or someone trod on the plug ro something. Check the pad or track hasn't lifted, actually physically give it  a wiggle, cause sometimes those suckers look like they are fine, until you wiggle them and they lift up! Next port of call would be the cap!

Good Luck

If he used the wrong polarity, you may just need to change the polarity protection diode if it has one, if it doesn't, that's a bigger problem.

If he used AC, you are probably looking at a rather large debug.

If he used over voltage, anything not rated for whatever voltage he used may be dead by now.
