I just acquired a Xerox 3600 Photocopier counter, the semiconductor version of the older Trochotron based 2400 unit - it has similiar/identical function when counting copies made.
Now, this unit looks like it has been sitting in a car shop or an old attic/barn for many years. I did clean out a lot of spiderwebs, egg sacks from spiders and a few flowers and sticks. Some of the TO18- & TO99-cased semiconductors have started to get small green blobs on them, probably from copper corroding, and some have started to rust due to their iron casing (2N3054s). There is also a lot of dust and what looks like some thin oil over a lot of the components and circuit boards. I'll check all of the components for function and replace as few as possible to keep it as original as I can. Some of the Mullard Tropical Fish capacitors have broken and the legs have come off, one transistor has had one of its legs cut off for some reason. Last week I got a bag of these Mullard capacitors when I bought older components for another restoration project so now they too will come to use. Now, I've never had to do more than some dusting on other old equipments that I've bought so now I need help from "experts" on what cleaning liquids to use to spare the components and circuit boards. Photos doesn't work in Neonixie-L for me and some other memebers so unfortunately I can't include any just yet (time to move from Google Groups as it is working so poorly since their new design?). /Martin -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
