I have read Mr. Slones book and I will be taking more classes next semester about basic electronics, so I don't have boatloads of knowledge.
Regarding the power supply/transformers and calculations for VA ratings, I noticed that if the current was higher ( ex. 5A and 100V as opposed to 4A and 125V) the wattage output is higher. As I am new to this, I would just like to understand how this happens. But after looking at the Seal electronics site, the VA rating and the secondary voltage was lower than what I was calculating, which was odd to me because I just worked the problem both forward and back and was getting higher numbers. Is there a broad range of numbers to use for transformers for a specific power output?
Also, is it possible to increase the power supply, but leave the amplifier circuitry the same to increase output? Or is there something aside from power output thats dependent on an exact amount for the voltage rails inside the amp circuit?
Thanks for any help.
