Adding a grounded power cord to my Korg Delay??

Soo.. For a while now ive been wanting to change the 2 prong power cord in favor of a 3 wire cord.. Finally today, i picked up the pieces i needed to do the change but i'm not sure exactly where things are supposed to go..

Do I just reattach things how they are now but use the third wire and ground it to the chassis?

I havent opened up the unit yet, but i'm going to do that right now and snap a few pics..

Any help would be awesome..

Here are some gut shots of my Korg Unit.. This seems like a fairly straight forward mod.. There is a lug on the chassis that has soilder on it already, you can see it right in the upper right hand corner where the power cable comes through the back of the unit.. (second picture)

The 2 prong cable right now is attached to two points, AC-C and AC-H..

Here are pics..

There has goto be about 20 trimpots on the inside of this thing.. freaking nutty!!

That was easy..

For anyone who wants to do this mod to any (i'm assuming) multi-effects unit, its really simple to do. Just make sure the black (hot wire) goes to the lug on the PCB that goes to a fuse and then on to the power transformer. Attach the white wire to the other lug and then the green wire to the chassis. Make sure to triple check everything with a multimeter!!!

My unit is now hum free

Good job, Saturnine! I don't get why they didn't use a three-prong cable to begin with.

I was planning to start a similar thread about an old tube amplifier I own. It was made in 1975 and everything in it is original (other than the dust and occasional dead spider).

I thought that I would just need to be sure the ground wire went to chassis ground, but I'd like opinions from you guys who are more familiar with this stuff. So far I've only tinkered around with DC stuff and when I swap out ceiling fans, lights, light switches, etc, around the house, I turn off the circuit breakers for the area I'll be working in and make sure I hook up everything correctly.

Yea, alot of the info i found on google was how to replace a power cord on older fender amps.. Seems in amps, its best to ground to the power transformer rather than the chassis itself.

Do a search i found a bunch of stuff
