Line out question on Tube 5150 II

[RCAGuy05]

I want to run the preamp out of my 5150 II into a processor that does stereo panning and then run the L and R outs into seperate solid state combos. For a stereo sound. Now if I'm just running the preamp out on the 5150 head without any cabinet or anything, just the head itself on soley used for its preamp out, could this short something or fry the tubes?

You still need to be driving the speaker. There's no way around that unless you put some sort of dummy load on your amp.
