right I was talking in the chat section with some of the other members and i have gotten confused about what transformer rating I should get.
Right So It will be used in a 120W per channel Stereo Audio Amplifier.
It Produces 120 Watts into 8 Ohm, therefore 30.983 Volts, at 3.87 Amperes.
It requires a dual PSU at + and - 55 VDC, so before rectification thats about + - 38 VAC
so each secondary winding I need to be rated at 38 V, 3.87 Amperes, i.e 150 VA, is that right?
so In order for me to have a Dual PSU for a single channel I will need (2*38*3.87= 295 VA) around a 300 VA transformer, so for BOTH channels will i need around a 600VA transformer??
