Using blown cab?

[krstko]

I have a stupid question. Can you damage a head if you use it with a blown cab? I got myself a free 410 cab, but 2 speakers are blown (one makes wierd hissing noises, one is just quiet). I would use it with my Hartke HA5500, only for room practice. Can I damage the head if I do it?

At least disconnect them and tape off the leads.
Shorts vs open circuits are not good.

For you tube guys--- I know-- tubes don't like infinite z.

I'll do that, tx for advice
