Did Marshall fix the jcm100 ground problem with the dsl100h by 2016?

Hello everyone.

I know the jcm100 had a problem with the ground for the speaker outputs and it was as simple as soldering a jumper wire connecting all the speaker out grounds which would prevent major damage. I also know about the conductive board issue but that's another story I don't need to get into right now.

So anyway, I just removed the little loudspeaker output jack board from my 2016 dsl100h and did a continuity test from the 16 ohm jack ground to all the other grounds and I have continuity on all of them even with a plug or a 1/4 inch wooden dowel inserted into the 16 ohm jack.

I thought once a cable was inserted into the 16 ohm jack then the other 2 Jack's had no ground... which caused the problem if the 16 ohm jack wore out and you tried using the 8 ohm jack(s).

Did Marshall connect all of the output jack grounds on the dsl100h by 2016?

Any help is appreciated.

Thanks.
