JD Sleep sells a ready-to-solder PCB for the May Queen, shown below.
Here are transistor pin voltages from the above build (using a regulated power supply that measured 9.10v):
| Q1 | Q2 | Q3 | |||
| C | 7.10 | C | 1.37 | D | 5.52 |
| B | .629 | B | .628 | G | 1.64 |
| E | 29mV | E | 0 | S | 1.41 |
W. Percival kindly contributed a PCB layout (PDF, 53k) for the May Queen.
Note that this layout differs from the PCB sold by JD Sleep, which was designed by Dean Hazelwanter.
