[QUOTE="Murray, post: 1029931, member: 3345"] So... boards are in. Outputs are +5 100mA -5V max 40mA. recommended 30mA or less. Perfect if you consider the filters draw about 20mA. The 555 oscillates at around 45KHz Idle current consumption on the 12V input is 10mA (1mA of which goes to the LED.) There was a mistake on the schematic: Pin 2 and 5 are connected, but it should have been 2 and 6. I made a mod, and could get the data needed. The first batch of PSU boards will all unfortunately include this mod. R0.1 will correct this silly mistake. [/QUOTE]
