10W 60Hz 120V

All xfmrs are actually a single unit having a 120V winding, a center tapped 24V (12-0-12) winding, and a 5V winding.  Class 2 xfmrs of this type are pretty common.  I found mine in a dead frequency counter.  Mine actually has two 120V windings for 120/240V operation but it wasn't necessary to show that. I built the inverter to run a single mains powered LED bulb and it did fine. I used BUL381 transistors but 2n3055 or any number of others could work with minimal adjustment.
