I have that book.That circuit appeared in an old Engineer's Notebook II sold and distributed by Radio Shack and written by Forrest M. Mims III first printing 1982 pages 34 & 35. There is a three digit, half the complete version, also. I actually used it along with a reflective photo cell (LDR) circuit involving V to F. When I used it it worked fine. The V to F was a FV9400 I think. That was a long, long time ago.
