Question: Pathos Classic integrated amp models

Can anyone tell me if there are any indications on the integrated itself that could identify if the unit is a Mk III or MkII generation?

Thanks if you can help!
I wrote the review of the Classic One MkIII in Mono mode for, and if I recall correctly the MkIII is distinguishable from the previous iterations by the plastic encased binding posts. If the unit does not have the plastic on the binding posts it is not a MkIII.

To be certain you could obtain the serial number from the unit via the seller, and check with Pathos. A legitimate seller should have no problem with assisting in doing so.
Doug is correct about the binding posts, also the MKIII has a taller transformer and the knobs are chrome, while the MKII have gold knobs.
