The background to this is that I am attempting to reproduce the amp in the schematic for an arcade machine restoration. These things are now quite rate and difficult to find.
You may note that in the power supply schematic there is a note that this schematic is for an amp running of a VAC toroid transformer but it was also built to run of 12VDC. Of course I need the 12VDC type. Given that I am guessing the coil referred to as replacing the bridge rectifier is an inductor or choke. My question is how do I work out the best value for this component. Power is comming in from a pretty basic switched PSU.
