Hi, sorry to take so long to reply to this....our house is a total mess after a new kitchen (ahem). Cant find any thing on the Duke website in the tech pages before year 2000... and even worse, there is no exploded diagram in the factory tech manual that I have......I've scanned a page to give you a flavour of what is in the manual and will scan the relavent section if they are any use...... I'll have a browse and see what else I canfind. Good luck - Frank |
