[quote author="thermionic"][quote author="Flatpicker"]Is there one for power supplies, or did I miss that?[/quote]Are you volunteering to start a psu META then? :wink: [/quote]Hmmmmmm... I suppose I could start one if no one else wants too. We probably need one, don't we?

Great!

Thermionic,

If you add all these suggestions to the first post in this thread (the "real" meta), I'll clean up all these other suggestions and posts. This will make it all more readable..

There's a fundamental mistake on this one... You can NOT make rev log pots by adding resistors to a stock pot. This was discussed at length last year at TT.

I left out bendy pots as it's a controversial topic, wanted to keep the thread within the realms of bread-and-butter links.

Time to get scrubbing Jakob!

Thought I hadn't seen it here yet:

Op Amp Applications Handbook, edited by Walt Jung (Newnes, 2005):

more Jung-pdfs (or buy the book):

There's also a chapter on opamp-history, including hollow state opamps.
