yep, thanks Mike, have used those before in bigger applications...

The good news is I worked things out, thanks Ian! The placement of the "ground screw" sticker was closer to a different bolt which was the incorrect one. I had been trying to remove the wrong one.

I thought it was strange as the original amp that came with the ep600 was a phillips. Well, it turned out a bit further away is another phillips head screw which is actually the ground.

I will be testing tonight to see if the hum in the other speakers has vanished... thanks all

Do NOT punch out on this screw, it is way too small and in an amp plate. if the reverse bit doesn't grab, get a drill bit and take a LITTLE bit of material out of the center, keep in mind the size of screw your dealing with.....

using a punch is find on larger materials. However, i never use that approach, i always drill a little bit for the back out bit to have something to bite on to. Sears should have backout bits.


Sheesh! I didn't mean to go all Thor on it. LOL!

I have a micro-punch set (for lack of a better word) and a hobby hammer that I'm quite confident with. A drill will work fine as well if you are careful with the speed. Not disagreeing with you. Just pointing out that it's good to understand another person's option before you jump all over it.

Murph, i know what your saying.


However, i've seen guys do something similar to this with a punch (a real one); not realizing how delicate something of that size is. I didn't want him to use a hammer on the amp plate. When most people read that they would not think of a micro-punch set.


I didn't want him to cause any more damage.

And yes, your 100% it's all about perspective.

The PorterPlex is once again "dead" quiet with no speaker hum with no inputs playing. Now I have to calibrate this new amp for my 600. smile
