Kits to start an audio electronics lab GB

[ashaw]

I have been thinking and looking for kits of components that are suitable for experimentation for an audio electronics lab. The problem is that such kits do not seem to be available in suitably high quality for audio. So I hereby propose the following kit GBs so as to get more people actually designing stuff.

A resistor kit:
CMF55 1% 50ppm in E96 between 10R and 5M

A capacitor Kit:
Ceramic NP0 50V 5% in E12 between 10pf and 0.1uF
Ceramic X7R 50V 10% in E6 between 10000pF and 10uF
Film: Polypropylene 400V 5% in E12 values between 1uF and 100uF
Aluminium Electrolytic - 50V 10% in E6 between 1uF and 1000uF Panasonic
Also 10*15000uF 50V Panasonic Electrolytic Caps

An Inductor Kit
Toroidal between 100nH and 4.7uH through Hole E12 - PCB mount
Toroidal between 0.10mH and 4.7mH wire Mount

A transistor Kit
Some common transistors, so Jfets, Mosfets and Bipolars. signal and power types.
