replacing +15v regulator on BA-11?

Oh for %deity's sake. This thing has only a handful of components. It probably took you longer to get the 'replacement' out of the other BA11-K than it would have taken to fix the original thing... I am not that 'hot' on conservation, but I do believe in replacing as few parts as possible. And that means changing a capacitor or a 3-terminal regulator, or whatever, not a PCB. Please don't module-swap classic computers (this rant has been here before, you won't change my views on it, I've seen the unpleasant reuslts all too often!). Yes, if the reason for it being low was that you'd added extra loads. No, if the reason for it being low was component failure in the -15V brick. Asjustments rarely, if ever, drift. If some voltage is out of spec then there's a reason. If it's something you did -- like adding an extra load -- then yes, you use the adjustment. But if it's just gone down while the machine is in use, you need to find out why. A dried up capacitor in the brick probably. -tony
