starting equiment that ic cold from being shipped

Regarding the cooling fins - yes they will work in reverse during the warm up but would only be effective if the amp is out of the box. However the fins would also increase air movement around the amp and thereby increase the likelihood of condensation. 

@feldmen4   Wow, thanks so much for this detailed analysis.  My balloon just popped however.  I've been awake for hours thinking that today is the day!  I have kept both boxes sealed as I completely agree that keeping things wrapped will hinder condensation.  I must tell you that the amp has been shipped to Krell 7 times between 2015 and 2021 for repair/recappping/etc.  It has been an audio nightmare, but I so love the combo of the KCT and the FPB 300CX that  I have refused to wave the white flag.  I'm pretty sure they don't pack it back with desiccant after repair.
Waiting 3-4 days seems like torture after so many absences.  I will say that Krell suggested 24 hours.  I spoke to a dealer in Milwaukee (Ultrafidelis) and I spoke to PS Audio who makes DAC and amps.  The tech said he got what i was saying but hadn't seen it as an issue in their business.  I will say that the Krell has many more parts than their offering.  The dealer said if your amp feels as cold as a bottled beer from the fridge, he would wait.  Any warmer than that and he said I could turn it on.  My plan is to do it in stages...first standby for hours and then on but not playing music for more hours.  Thanks so much for your input and expertise.

My logic is very simple as I'm a simple guy!

My point is to take it out of the box and put it in a garbage bag to prevent airflow and then put it in the warmest part of your house.

Many moons ago while in the military I was an Avionics tech working on jets.
So I have seen first hand where an airplane flies high and the aft equipment bay becomes very cold.  We were stationed in North Carolina a humid place. After  cycles of this some corrosion can set in causing electronic issues.

Your amp is not an airplane and won't be subject to freezing/thawing cycles.

Apparently you love this piece, so I would take all preventative steps.
This is just my two cents, but it is what I do.  Enjoy the piece, I hope it doesn't require any further trips to Krell.

The cold inside surface is only exposed to a sealed area that is filled typically with argon gas to reduce re-radiation but it is also dry so there is no moisture ( water vapor) to condense on that surface (the inside surface of the outer pane of glass).

Technically it is more like convection or maybe conduction?

One can imagine the old video game Pong, and the pong balls carry the heat from one side to the other like a pack mule.
The argon pong balls are slow and carry heat from one side to the other in each bounce.
The helium pong balls move faster so we get more bounces per minute.
So if each load of heat the heat on the mule is the same, we simply get more loads carried over time with helium pong balls than with the argon ones.

The fellows talking about garbage bags amd not opening the box, sort of doesn’t make sense to me, as I am used to seeing the devices wrapped in a bag inside of the box with a little bag of magic desiccant crystals.
If it is one of those similar deals here, then just keep that bag sealed.

The box and Styrofoam shipping protection, only insulates it to delay the warming.
