Thank you Hal, those pictures should have all the missing information, I can see they removed a double thickness ground trace from the front and made a much wider trace on the back, it confirms the 1826-1381 for U602. I'll check the resistors another night, getting late tonight here in the UK.
And Artek did have the correct manual, very quick response to my email and I now have an excellent quality manual covering the 1982-84 versions.
