Player gets hot after a couple of tapes

The 2nd 300 player I received today gets rather hot.
After playing 5 tapes from beginning to the end the player is pretty hot and the tapes are hot when ejected.
Is this normal?
The first 300 player I have does not get this warm.

DCC recorders may get warm but shouldn’t get alarmingly warm.

Is there any way you can measure the temperature of the heat sink(s) after it’s operated for a while (with the cover on)?

Unfortunately not.
I don’t have such equipment.
