If you have had 1000 Amazon click and no sales, I'd consider switching to E-bay.
However why not try it on your most popular hubs, where you are getting the most traffic. Its the easiest way to test it out without going through all 189. If it works with your test hubs, then start to change them all.
With regards to Adsense, if 1000 people are leaving your hub via a link (rather than just closing the browser or clicking Adsense, there is some logic to the fact that Amazon is stopping you making money. Again, try taking Amazon off a small number of your hubs and see if your Adsense revenue increases.
Don't expect miracles in the first week or so, but see how it goes.
