You got the right size!!!!!
Power wires do not get warm if they are the right size , the amplifier has an efficiency factor. The lower the efficiency factor , the warmer the amp gets because all that power that does not leave the amplifier has to go somewhere , it goes to the heat sink. If it was 100% pure efficient , ALL power would be leaving the amplifier , thus no heat would take place...Think SUPER CONDUCTORS!!

307 may I?
Pc what 307 is trying to say is that when power is applied to a use and not all of it is used entirely some of it is converted to heat due to resistance in the wires and components. So when you apply power to a final tube and only 40% of it is passed on down the coax to the antenna the other 60% has to go somewhere or do something. It, in the case of a final amp tube, is converted to heat. Hmmmm think one of those inexpensive electric heaters. The resistance/ineffency of the heating elements to allow electricity to pass thru it makes them convert unpssed juce into glowing hot heating elements.
Which is why we put little fans on tubes to cool down that hot tube. The more efficient the tube is the less heat that will be generated and the smaller the requirements of the fan to keep it reasonably cool.
So if your amp is getting too hot for your liking you might attach a computer cooling fan to the heat sinks of the amp and power it via a tapping of a non critical circut (an indicator light or such) with enough voltage to make the fan operate automaticaly when the amp is turned on. |
