Just an update on my component sourcing, i thought you guys might be interested in:
After spending much time searching for my bits, i wanted to recommend 'small bear electronics' and 'futurlec', i found quite a few companies that stocked the obsolete parts that i needed but i would have had to have made minimum order of 75-100 which was way beyond what i needed, the companies above do 1's and 2's off if thats all you need, the postage came to more than my parts though.
Oh yeah, when my LM3900 arrived, i was so excited, i went straight to my workshop and swapped out the LM324, i powered up the circuit and ........nothing!!! after scoping around for a few mins, i realised i had laid out my veroboard for the LM324 and they arn't pin for pin replacements.....DOH!
Now i have to start again and lay it all out for the new device, i hope i havn't destroyed it! although i did buy 3 of them just in case.
