I'm about 99% sure that is the case - Mesa uses a clever trick with tiny transformers to generate isolated gate drive for the MOSFETs, so it doesn't matter what you have on the load side. I suspect they would even work with nothing but an ohmmeter connected - not many solid state outputs will do that.
