2/90/2 power amp oil like fluid seeping from power button

What fluid could be seeping out of the power amp main power switch. Minor amount of oil like fluid. Just got this power amp in August brand new.

It is worth noting that it is not constantly seeping. Just noticed there was an oil like film on the green main power switch but nowhere else. Wiped it off and the amp is working.

Just want to know what it could be. I don’t tour with this unit so not sure what it could be. Is the power transformer behind the switch and could have leaked something?

Thank you for your time.

There is a small amount of grease on the non-metallic parts of the switch assembly that can make its way to the surface when the amp get’s hot.

It’s just there to reduce friction on the mechanical parts. Once you wipe it off, it should stop seeping out.
