Hi,
silvered mica seems a surprise!

Compensation resistors of 20M and 100M will take some sourcing and clean boards.

Found this. It seems to be pro tantalums (personal opinions aside) on this page http://www.zero-distortion.com/tests.../opamps_07.htm

Why tantalum, I hear you say? Well, tantalum caps are easily the best thing around for decoupling - open up any professional grade electronics unit, such as measuring instruments, medical equipment, or communications electronics, and you will many of them all over the place. Tantalum caps are not much good for anything else, and they can produce funny results in audio circuits when put in signal paths, but they decouple like nothing else, only a proper gyrator (sometimes also called capacitance multiplier) being actually better (but also VERY hard to get right).
