I've been busy with work so no real progress yet. In the meantime the postman delivered the capacitors I need for the Thorn so I can now proceed on its repairs.
I've also been most fortunate to obtain the service manual for the Korting from a retired TV serviceman I know. As suspected the missing module "R" contains the power regulation circuit for the line output stage as well as a line derived 12v supply for the horizontal oscillator. The circuit is fairly simple with three transistors and two SCR's so I can replicate it sometime.
The manual also has a drawing of the module with the PCB details so it will be quite feasible to etch a replacement one rainy day in the future!
