Incorrect speaker cable connection can damage amp?

Dear Audiophile gurus,

I recently bought a tube integrated amplifier and
mistakenly I connected the speaker cables to the amp
outputs incorrectly; my amp has outputs for two sets of speakers as follows:
...............---- A -----.....................---- B -----
.set 1 ---> L..o....o..R.....................L..o....o..R
.set 2 ---> L..o....o..R.....................L..o....o..R

and when I first tried to hook things up I connected
for the Right speaker L to B1.R and R to B2.R and
for the Left speaker L to A1.L and R to A2.L

Can this cause any damage to my amplifier?!

Thank you in advance.

It looks like you either connected them out of phase (plus (RED) to minus (black), and minus to plus) which will do no damage, it just may sound a little thin; or you connected the left channel to the the right speaker, and vise-versa, which is OK also.

If you connected one speaker in-phase and the other out of phase, some sounds will just cancel each other out (in the air).
This is OK electrically also, it just won't sound right.
