do you warm up your ebs valve driver?
 

Hey dudes,

I've just got my ebs valve drive though, I was kinda expecting to see a note in the blurb to say, 'turn on thirty minutes before using' or something similar, but it didn't

Can you just turn it on and use it straight away?

It may take a few seconds to work, but they're just tiny preamp tubes, not a power tube, so no, no need to warm up.
