Re. posts #93, 94 and 95, I have just noticed that the schematic with the single 7k5 resistors and R3 = 100 ohms has a 500uA meter. All of the other schematics have 200uA meters. My guess is that the one with the 7k5 resistors and 500uA was the earliest of those under discussion.

Good luck with the search for information on the 159. If you find anything, please report back.
