Zenith Integrator - Replacement

[bhegges]

Here is a little project I did for replacing Zenith integrators using an ExpressPCB designed circuit board, I was able to sneak these on to a larger project board. Assuming the data I found on-line is correct these should work nicely. Note I could not find values listed for part number 87-9 but elsewhere I saw 87-9 was replaced by 87-8.
