I do not have any experience with toroidal power transformers at all. I am building a 300watt power amp and need some information. I bought a used toroidal transformer that is 32v-28v-0-28v-32v secondary. It is "300VA" 120v primary and is only 120v. I will be using the 28v-0-28v part of this transformer. Am i right in assuming that the 0 "CT" works as the ground on the secondary winding side of the coil? Also my power amp schematic calls for a 30v-0-30v 10amp transformer.
The person who sold me this power amp kit told me to buy a "300VA" 28v-0-28v transformer but i am also wondering if the amperage is sufficient for the 10amp transformer that the kit calls for?
One other thing is that when I read the secondary voltage on the 2 x 28v lines, it is correct reading from each line individual and grounding to the 0 "CT" line, but when i read the lines that are supposed to be 2 x 32v each, each one reads over 60 plus odd volts also grounding to the 0 "CT" line. Am i doing this correctly?
I would appreciate your help in figuring this out and i also want to thank you ahead of time for any help given!
