Probably been found long ago, but has anyone else noticed the K7000 schematic has R74 listed as R14? It's a 22 Ohm by T2. The real R14 is over by those 3 BiPolar caps.
I just noticed this when looking at the K7000 schematic and the one for the K7191 floating around (which,although a poor scan, has it as R74 correctly).
BTW, the real R14 is listed as a 1K on both schematics and the parts list, but the color bands on R14 on two different boards I have (K7197 & K7131) indicate it's 470 Ohm. The bands are yellow, violet, brown, gold. My eyes are getting old, but that's what they both appear to be. Those measure in circuit as 451 & 473 Ohms.
