A suitable power supply that provides isolation from the 120-Vac line is shown. The circuit uses two filament transformers connected back to back. The secondary voltages can be almost any value, as long as they are equal. A 1:1 isolation transformer can be substituted, if available. The transformers should be rated at least 25 VA or more.
