Trinity Supreme amplifier

Dieter of Trinity Audio insights on the dealings with the heat in his Trinity Supreme amplifiers. 
“The standby power consumption is roughly 200W, which is caused by the high bias current. This heats up both heat-sinks to roughly 60°C. At full load of 200W into 4Ohms the Temperature of the heat sink will be in the range of 70°C at an ambient Temperature of 25°C. That is the worst case. Of course I do additional thermal measurements before I mount and ship a power amp. Enclosed the first thermal Picture I do during the assembly. It shows all the Transistor pairs and the related voltage Regulators in blue. This Picture was done at reduced supply voltages, otherwise the Transistors get too hot. Means for all further measurements I have to add the heat sink.”
