Just a little bump to this thread. It looks like someone made a serviceable upgrade for the 2510/2520 opamp

The caps are marked on the sample that I have (from a Legacy that has decided to start EATING them almost daily - expensive little habit). The above link did help decode them accurately
Per the schematic posted on page 2: C1 = KA5 = 0.1uF, C2 = VS1 = 47pF, C3 = VA2 = 100pF.
Also, C3 is between Q6 emitter and V+.

A note to follow up
The 2510 is used as a summing amp in the legacy boards with a +/-28V supply. This is often turned down to +/-24V, still way more than most chip opamps can handle today.
Cheers
