What "bench" reference information would be useful to you?

I keep several charts and diagrams near my workbench. They include resistor color codes, cap codes\conversions, a simple tranny substitute chart and over the years I've compiled a list of opamp substitutes for single, dual and quad opamps. Common wiring diagrams would be a good thing have; I've not assembled a folder of common wiring scenarios and always need to dig up an example. Another chart I find handy is an inches to mm\cm conversion chart - that stuff always messes me up.

For the tranny subs, I use this chart (that may prove beneficial):

And here is the opamp PIN-FOR-PIN Replacement List . . . .

TL084 - Slew = 13V/µs
OPA1644 - Slew = ~20V/µs
OPA4134 - Slew = ~20V/µs

When deciding to use an alternate opamp, I always reference the specific opamp's datasheet. The list above is just a quick reference.

Thanks for this.

Color Codes for resistor might be handy, though I prefer to just measure them if I am not sure what it is.

What I look up EVERY SINGLE TIME is the pin-layout for pots. I just cannot remember that darn thing.

Common voltages for ICs would be super cool.

I'd like to think that looking up common color codes etc is on us but I agree that possible substitutions for less than common parts as well as bias/trimmer notes is really helpful. It's good to know that there's always help readily available on the forum here but target values are always good.

I would recommend everyone who has a smartphone to get DigiKeys app even if you don’t buy stuff from them. It’s got resistor colour codes, current divider calculators and all sorts of cool stuff as I agree that stuff falls on me to find out.
I have a printout taped to my pegboard of all the diameter sizes for all the holes to punch on the enclosure.

I've been using an App called ElectroDroid (even had it on my windows phone) for about 8+ years. Has all kinds of calculators, pin-outs, and resources.

I keep an old junker laptop filled with .pdf files of all these charts, schematics, product whitepapers; .gif's of schematics and layouts; anything I find. I also keep OLD cross reference books, pre-internet stuff, in book form on a shelf - nice for restoration work.
