I know that turning a "TUBE" amp on without a speaker load on the output will damage the amp.

(the no-load condition will cause the output voltage to increase until the output tubes burn out, which can then lead to other component  damage)

Is this also true for a CODE 100 amp?  Is there a risk of damage to the output section, with turning the unit on without a speaker cab load connected?

Would it be safe to operate the amp with just headphones connected instead of a speaker cab?

Would it be safe to operate the amp without either a speaker cab or headphones connected?

I ask because my computer (which is a desktop) is in a different location in my house than my amp.

Doing firmware updates or testing out patches requires either moving my computer or my amp, both of which are very inconvenient.

It would be much easier if all I had to move was the head.
