Yes you can exceed the printed limits on each output, but there are limits. Each output has a linear regulator, so you can exceed that. Also, some outputs share the same tap from the main switch mode power supply transformer (ask described in another thread by Poul Cioks. If you have tube pedals you will likely find these limits, if not you won’t. A few examples, trying to power a 12v 500mA Kingsley jester from the 200mA output did not work. Trying to power 2 500ma 9v Kingsley pedals from each of the 9v 500mA outputs did not work. This was both on Truetone cs7.
