Well the scraping and squinting finally bore fruit. I managed to meter out the film resistors and rounded them to the nearest commonly available values. The transistor i managed to destroy whilst removing it but i just replaced it with a common NPN BC548 and it seems happy enough.
For anyone wishing to fix or build a replacement this pic should help. The grey boxes are the 0 Ohm links.
I ended up fixing the original hybrid rather than building a replacement. It works a treat .. yay !
