Sorry, they're EL34 tubes in both.
I've heard that the Orange Rocker 30 was based on a Vox AC30, so I assumed it had EL84's in them.
EL34 on the left from Orange Rocker 30, EL34BHT on the right from Orange Rockerverb 50 mkII on the right. (I have no idea what the difference is!)
[edit:] here's some EL84's courtesy of Dr Internet...
