Recently two people have fried their power transformers by hooking them up to the 4-diode bridge rectifier designed for the VJr PT on the Baby Will pcb. The Baby Will build manual does NOT address the need to remove diodes D3 and D4 if you are using a center tapped power transformer.

Always use a dim-bulb tester for first power up that would have shown that the above transformers were shorted out and saved the transformers.
