Some maybe useful links
2004-10-01 by Larry Troth
I am posting these links in the hopes that some of you will find them useful in your search for parts and part information. This is not a sales thing, I have no relationship to any of the companies behind these links. Look for semiconductors from common suppliers and get price comparisons: http://www.findchips.com/ (Please note that you can also search for non-semiconductor parts. Searching for 112A brings up an interesting list including several sources for Switchcraft 112A jacks.) This next link would normally be used for Business-2-Business to find parts. Maybe you can find a local distributor that would sing up, or maybe you can try to buy parts with the trial membership. You can get availability info without a login so at the least you can see if the parts exist! (There are LOTS of CA3019's out there!!) http://www.hkinventory.com/public/home.asp And saving the best for last, ever looked for info on a semiconductor and couldn't find it, the following site has a better listing they anything else I've seen, and it's free! http://www.alldatasheet.com/ It really is amazing what you can find using Google and a little persistence on the internet! Have fun all! Larry T.
