in the Datasheet - the 7107 calls for the use of a 100pf capacitor however I found this to be far too slow at responding to a multiturn pot in a power supply so I replaced this with a 10pf capacitor which was much much better - meaning of course you don't have to mess about with trying to get accurate readings from the adjustable power supply (if you use it in one) if you build it - try to ignore the displays I've put on the first picture - they were for my reference and it was possibly a very specific display (I tend to use salvaged junk)
I've also included a couple of pictures of things I've used it in.
