These power supplies suffer from Dried up capacitors on the secondary side of the Power supply, When these go, Mainly the ones for the 5V (CS21,22 = 1500uF 16V and the smaller 220uF CS20) they cause the primary side to become u|

|15-01-2011||I'd confirm that all power supply secondaries are trying to come up and that there is no other heavy loads stopping them. Also regulator failures.
What happens IF you were to keep the relay energized? (either by putting a jumper or your own voltage to dr|

|16-01-2011||There is no set standards on numbering on SMD transistors. While there are several databases available, there is no guarantee that it may be the same transistor you are looking for? For example there is a "625" on zetex/diodes inc--one of severa|

Seems a little high, don't it?
?PPD3? - now, or ?PPD5? earlier. Or do you mean both?|
