I just posted this to the DotComFormat group and thought that some of the
members here might be interested. Please forgive me if this is off topic.
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.aspAnd 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!
