Thanks for your reply, wow that is quite the haul you have there. I'm keen to buy some tips off you.
I actually got my unit in 2009, it was missing the glass tube for the de-soldering iron. At the time I got a replacement tube and a spare hollow tip from techtron.net.au, they don't appear to exist any more. I must have a paper manual somewhere since I found a scan of the parts page for the "de-soldering tool - CT204&M" in an email when I ordered the tube.
I would love to get a spare tube for the de-soldering iron, the one I have wasn't bent correctly but I've made it work. I've always been worried it will get broken and not be able to replace it. I've been meaning to find a local glass worker to see if they would be able to make a spare for me. My de-soldering iron is labelled CT204 and Rd.83.405, tried taking a photo of the number but bit difficult since it is behind the cage.
I've only recently started using this iron again, hence looking for spare tips, all my electronics stuff has been in storage for about 7 years since we moved, starting to get to play with my toys again and dig stuff out. Had to solder in a SMT cap the other day and even the 1.5mm tip is too big really, which got me on to looking for replacement tips.
Your mention of circuit diagrams makes me think I do have a manual, I remember seeing circuits, thinking, that will be useful if I need to repair them and that most manuals now don't come with that sort of information. I'll need to dig through my other boxes.
OK, should have attachments this time, had to reduce their files size!
