I used to own a DL4 that was rated as 9v AC 1200mA minimum with a Godlyke powerall power supply that was 9v DC and 2000mA.
It worked fine, there are even videos of it working on their website.

However I recently sold my DL4 to upgrade to the M13 (I sold a few other bits too to finance it...).

I contacted Godlyke about powering the M13 with the PA-9 and they said as far as they knew it wouldn't harm the unit,

but they could only confirm that that the PA-9 works with the M9 and haven't tested it with the M13.

From what I've researched I can't see any major difference between between powering the DL4, M9 and M13.

They may draw different mA but all run on 9v AC power.

Has anyone had any experience using the Godlyke powerall with the M13? Would it work or am I headed for disaster.

I tend to think that the M9 and M13 can't be that different and it should work.

I'm prepared to use the Px-2 power supply that the M13 comes with if need be, but would prefer to power everything off a single unit if possible.

Had a great experience with the PA-9 and would be a shame to under utilise it.
