Your new tubes are drawing less current, thus causing your transformer to run cooler. I am sure, if you wanted to, you could increase the idel current and get the transformers hot again.

So I guess I will have to live with the cooler transformer. My only concern would be is the cooler condition a bad thing?Sound wise the amp is just fine. In fact the JJKT88's sound to my ears better.
Seems to make a case for manual biasing if in reality one would want the transformer to run hot. I realy don't know if this is a bad thing to run cooler.
Should I put the old EH tubes in back because the cooler condition is bad long term?

Heat is an enemy not a friend in most cases! I wouldn't be at all concerned. I'll bet the output tubes run cooler too. It's very possible that one (or more of the old tubes) was drawing excessive current.
