Power Supply For TC-Helicon Harmony G-XT

[tpandela]

The power supply for my above unit went south on the gig this past weekend and, well, I missed it. I found, and ordered,  a replacement part on Amazon but it probably will not arrive until after next weekends gig. The original power supply is rated 12V, 0.4A and 4.8W.
As a test I plugged in the 9V power supply from my GT-10 and the unit booted up, same with the power supply from GP-10 and my Zoom G3.
So my question, to those who understand this stuff: Will it harm my unit if I use one of these power supply's for Friday's performance?

Thanks in advance.
