The PWM controller is a TL494CN, Chris, so I can easily find data for that, but the tiny 6-pin SMD chip associated with the CS1N60 may be a different kettle of fish. I've already identified the connections to 3 of the pins of that device. These connect to the source & gate of the 1N60 via series resistors (to be precise the pin connected to the source is effecively grounded via the 2R0 resistor via a series R of510 ohms). Two of the remaining pins must surely be Vcc+ (or Vdd+) and ground, so I'm (slowly) getting there! Thanks again to you and other members for your help.
