CA3035 substitute.

Sorry I searched All my Files.
I still have the Basic Schematic and my original PCB Artwork, but I can't find My Schematic showing the Part Values.

It must have been on one of my older computers that Crashed.

I usually keep Assembled PCB's Samples of most things I design, But I also can't find that one their.

UPDATE: I Just Found the Schematic, where I Posted it on Geotech years ago.

I Designed, Built and Tested this Circuit.
It appears to work as good as the Original CA3055, But I Do Not have a CA3055 to do more Conclusive Testing and Comparisons on it.
