As a former poor student DIYer, I survived on the following, and could get 90%
of Electronotes circuits cobbled together :)
RESISTORS
100K 1% <<<needed for those pesky 1V/Oct summers. I got some TRW 0.01% 1W parts
surplus for 10 cents (the 1974, that is. The list price was over $9ea!!)
1K
10K
1M <<<these 3 resistors (and the 100K) are probably 40% of the resistors used
in the free world
then get some filler resistors:
3k3
6k8
15k
33k
68k
330k
for caps: youreally only need to get 3 kinds to cover 99% of what you will every
need
10uf 25V electrolytics << universal bulk bypass cap
0.1uf ceramic monolythic axial caps << universal bypass
get an assoertment of Panasonic ECQP 2% caps from Digikey. These are my
"universal" analog design cap. VCOs. LFOs, VCFs, you name it, these are easy to
use, very stable, 2% tolerance (for multi-pole VCFs) and cheap. I used 12
*million* of them in old Tandy modems :) So, get
1nf
4n7
10nf
47nf
100nf
470nf <<< these will cover most of the range/values needed
Next you need
1N4148 diodes
2N3904 and 2N3906 transistors
TL072 op amps
TLC555 CMOS times <<< these 4 items are used in 99% of all synth designs in 1
form or fashion
All of these together, in reasonable quantities will be <$35

fondly remembers paying $2.85 for a 1% 0.047uf cap in 1979 (in 25,000pc
quantities)
