More gear these days uses external line lump supplies, but they almost universally omit an on / off switch on the unit. Curious as to why?
Certainly you can't switch mains voltage, but why not switch the incoming + / - 15 V?
Any reason the smps supply itself wouldn't like this? If not then all that's left is cost, but that's a strange way to save a few bucks on a high end unit.
