Thank you for your response!I guess you did not see the new schematic and parts list on the first page of this thread. If you cannot find the 28VAC transformer then use a 30V/4.2A (126VA) transformer instead.
So what kind of transformer do I needed to have an output of 30 volts and 3 ampere?
How about the parts were left, do I need to change it?
how about the components that will not use, i simply replace them a wire or what?
and Is there any changes in Schematic? Please reply? Thank you!
