Mc6 / 8 Power Requirements - Barrel plug type/size


I am wanting to use a morningstar mc6 or mc8 with line 6 hx stomp using external daisy chained power source.

My question is what size is the barrel plug for the power socket?

The Stomp has a 2.5mm x 5.5mm barrel plug with output polarity - Tip Negative.

Is the mc6 / 8 also tip negative and what size barrel plug does it use? Would it be fairly easy to use in a power daisy chain with the hx stomp.

Many thanks

I’m not sure on the tip size on the MC6/MC8, but they are tip negative and the standard size as the majority of my pedals.
The HX Stomp is different though, for it’s requirements I had to purchase this Current Doubler Adapter to power it off my power supply.

and this cable to convert the 2.1mm on the adapter to 2.5mm for the HX Stomp. CY 60cm DC Power 5.5 x 2.1mm / 2.5mm Male to 5.5 2.1/2.5mm Male Plug Cable Right Angled 90 Degree: Industrial & Scientific

So maybe the morningstar MC’s use centre negative 5.5 x 2.1mm?

Yes I have adaptors for hx stomp, one to change to centre negative and one to change the size.

Also I purchased a rip cord for my boss rc-300, it also works with hx stomp with the 2.1mm to 2.5mm adaptor fitted.

I checked on what cables came with my Strymon Zuma power supply and they are 5.5mm x 2.1mm barrel connectors, center negative. So that is what works with the MC8/MC6.
