So basically I'm looking to order a bunch of stock parts, particularly opamps, transistors, and pots from mouser. I'm looking to do mostly audio work, especially involving tubes, but I am also starting to dabble a little bit with arduino and micro controllers too. I know this list can go forever, but I'm just looking for a few suggestions on actual parts I could order.

Or better yet, what I should be looking for in the parts i order, that's what I would really like to know.

Hi,

DIY Audio is something cool but tubes projects are not for starters. They involve high voltages, expensive components and good wiring/soldering skills.

Opamp, transitor based circuits can be battery supplied, breadboarded and components are super cheap.

Here my part list suggestion

1/4Watt axial resistor

https://www.sparkfun.com/products/10969

or equivalent no constrain here

capacitor

Unless you do filters electrolytics one will be the most used

10µF / 100µF will be OK, go for 16V or 25V ones
100nF ceramic , general pupose
1nF ---> 470nF to do filtering


Pots

10K / 47K will be OK look if knobs are easy to get

Transistors

BC547/BC557 --> general purpose / any brand
MJE253/MJE243--> to build discrete audio power amplifiers /any brand


IC

LM386 super standard audio power amp / JRC have a bit more powerful version, ensure they are DIL package !!!
TL072 popular FET dual op amp /any brand, ensure they are DIL package !!!
NE5532 popular Bipolar dual op amp /ant brand, ensure they are DIL package !!!

few IC socket too, 1N4148 diode are also useful

You can have an idea of what order by looking at various schematics from this manufacturer:

like this exemple

For Arduino hardware side just buy a board, connectors a proto shield maybe, few leds and it will be OK to start.
