By this I mean the ones where you install it, then outside of routine maintenance, it just works and never asks for more. Boring….NVlt getting the 5.0 software update.Always move the Pusheen to the center before updating, otherwise you have to do it again. I don’t know why and I’m not questioning it. Yours doesn’t have a Pusheen on it? Uh, that’s a highly technical problem.Boring backplaneElsewhere, this Crown started losing its boringness. It started occasionally dropping output. I’ll be replacing it with a fully boring transmitter soon. I bet it’s not much more of an issue than a dried cap in the power supply.Note to self: print a Pusheen to leave on top of the new one.
