2600 repair suggestions needed

[Robot]

>When my 2600 S&H failed, I decided it was time to take on the task.
>I replaced the LM301s w/ LF411s, and clipped the comp caps (on the end of
>each opamp, between pins 1 and 8, not needed because the 411 is internally
>compensated).

Are there any other alternatives to the LF411 because I went to both a local
electronics surpluss place AND a new electronics shop and neither had the
LF411.  If there are any alternatives, please let me know.  Either that or
tell me where a good place to order LF411's.

Thanks for all the wonderful help everyone has been giving.
