What is the purpose of the heat sinks sitting on top of the Power Transformer? That much of difference, or just a whim?

yes when using in summer months they run hot and i have measured the temp to over 105 degrees with the heat sinks the temp drops to around 100 and in my past experiments and experience usink heat sinks and fans have helped prolong the life of my amps
i have a dynaco st35 still original with the last change of power tubes 18 yrs ago its still plays on spec and sounds awsome, i use some computer fans with old cellphone chargers the dynaco does not even get up to 85 degrees
i just retired my 3 altec 1569 amps from my home theater and these monsters ran for 20yrs with no problem
heat is the enemy for reliability as for sonics maybe 0.5% better on high end equipment
My guess is that the power supply is underspeced and gets hot.
