It is a model 662, my spare tube is a 14QP4, not compatible.
I powered it up on the Variac and it had a raster of sorts, it was pretty bright considering the tube isn't that great, it'll probably work OK if it was recapped.

It crapped out after about a minute and the 5U4 was getting red so no doubt the filters are shot but the basics are OK.
