I've now solved the problem, Mende, but thanks for the links to the various diagrams. The first link is certainly a diagram of a similar, but slightly earlier all transistor model. Other than different output transistors and o/p transformers over the years, the main difference is in the wiring to the 9 or 10 pin link cble socket used, principally the pins used for the dial lamp connections, and the 'automatic' (self-seek tuning) supply. Ironically I used to work for a Blaupunkt dealer as their service engineer, and had a whole load of service manuals, many of which are now gone!!
