I'll take a look at the schematic later, but have you removed the fuse?I am having a problem at the testing stage, where I have to use the trimpot to set 5v at the two PC stakes. The trimpot regulation is not linear at all - as I turn it from one extent to the other the voltage hardly changes at all until approx 2.4v, then it jumps very abruptly to 5.8v, before slowly increasing to 6v. It is absolutely impossible to set it at 5v.
