Hi Larry,

It is normal for most commercially wound power transformers
to be uncomfortable to touch under normal loading. The insulation
is generally rated for continuous operation at 105C (above boiling
point for water) your transformer is less than half that.

Mebbe it's not bad, just seems pretty hot after an hour or so. No
growling sounds. Temp of the shell is 47C at that time, and room ambient
23.3C. Uncomfortable to leave hand on it, but not painfully so.

Thanks for the info.
