A shamefull goof-up

I bought a Sony CRT Watchman with the paddle style CRT. IIRC, that's what they referred to the design.
I was experimenting with a lighter socket power cord that fit the auxillary power jack. The Sony has the center terminal negative, so I connected the power cord reverse polarity. I should've checked the connections on the power cord, as it turned to be the proper one, with the center terminal negative.
I tried the set with Dollar Tree "C" cells and it worked rather well. After reverse polarity damage, the display is now trapizoid shaped. It must have a different type of horiz scan circuit, because the yoke couldn't be damaged under those conditions. I'm not going to try to repair it.
I'll try to be more careful, next time, which I usually am.
