Rockerverb Tube Switch

I was thinking of trying some KT88s or 6550s in my Rockerverb. I know there's a switch on the back of the MKII so obviously I'd flip the switch to the correct setting and bias the amp. I do bias my own amps but I've never switched out tube types so are there any special steps I'd have to take?

Just regular biasing.
Be aware that some users have reported issues trying to bias non EL34 valves using the switch as it is intended.
I would follow the switch to start with, but if it keeps you too far apart from the normal range for the vakve type you're fitting, don't be afraid to switch it back.
