Fixing a "pothole" in a recording

[j.w.moore]

I've transferring some old vinyls to digital, in order to put them onto CDs. Mostly the records are in pretty good shape. However, on one particular track, there was some damage severe enough to cause the tone arm to keep skipping back to the same track repeatedly. I managed to record through it by increasing the stylus pressure ever so slightly, but now have a huge glitch that produces a very loud thump, much like hitting a pothole in the road. Any suggestions on how to repair this? It's way too big and complex for simple click removal or repairs. I've tried chopping out sections, duplication of sections to paste over it and everything else I can think of, but still wind up with an audible thump - much reduced in amplitude, but still audible. Any suggestions for repairing really nasty sections of track?

Thanks

I've tried..... duplication of sections to paste over it

That is almost the way to do it.
Rather than just pasting the "patch" over the bad bit, you need to put the "patch" onto another track and cross-fade from one to the other. I hope this illustration makes the process clear:

OK, I will give that a try. Thanks for the tip.
