Most of the transformers that we can get these days has that Center Tap removed. It is important to include 2 100Ω resistors in the circuit. It has been covered elsewhere, but basically, the two green leads from the Power Transformer run to the pilot lamps.

The 100Ω resistors go from each leg of the lamp to ground. The TAN Kits do the same thing.
