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.
