Why are the power tubes larger than the preamp tubes?
The power tubes put out a lot of wattage, so they also create a lot more heat. Our power tubes are made to handle about 25 to 30 times more wattage than our preamp tubes, so they must be larger. For example, say I have two pieces of metal: One is larger, and one is smaller. If I tried melting both pieces, which would take longer? The larger would, of course. All electronics made to handle extra heat, whether it’s a resistor, tube, transistor, diode, etc, will generally be larger in size. This is for reliability.
