Hi!
During my panic over the weekend, the name Royston Orme was mentioned more than once - http://www.ormatronixorgans.co.uk/
Whilst other people are very knowledgable and practical, Royston has versatility to his repertoire:
* Ahlborn
* Bradford Computer Organs
* Cantor
* Content
* Gem
* Makin
* Norwich
* Phoenix
* Viscount & Wyvern
Um. Does that leave anything that he can't cope repair?
Best wishes
