On an 11/70 I once ran, the +5 supplies had to be within .05 volts or the machine simply didn't run, and this applies to ALL the +5 supplies, of which there were at least 10 pots to be tweeked. So, while that requirements seems stringent, modern supplies can maintain the tolerance fairly easily, and the requirement itself isn't that uncommon. -Mike O'Dell
