Paul Another great video. I am enjoy them all, and I always learn something new.
Someone is very very confused
Interesting discussion. Always wondered why two amplifiers, one a tube and the other solid state, given the same wattage rating, the tube amp seems to sound louder and clips much later.
The B rail (positive high voltage on output tube plates) is usually many times higher than similar voltages across solid state output devices. That high direct current voltage, though filtered out by the output transformer, must create this apparent difference in performance per rated watt.
I use a 35 Watt class A amplifier that gives me ear splitting sound levels from my 86 DB sensitive Wilson speakers. I listen at a loud 28 of 100 setting on the preamp. Don’t want to get anywhere near those B rails though when they are cranking along.
Is this why thicker speaker cables allow a better free flow of current.
