So i scored all these parts out of the dumpster and was wondering if anyone recognised any use for any of them in a stompbox setting, ive looked up the data sheets/ googled but it wasnt to helpful
ive also been plugging the transistors into runoffgrooves multiface circuit seems none are better than a standard j201
im kinda interested in what these nand chips could do...
anyway heres the list of what i got, anyone recognise anything useful? i think the 8 pin op amps could all be utilized
trannies:
mm3005
c1047
c1312 x 6
d1302
c1318
c1359
a1689
bc238 x 13
bc237 x 8
bc338 x 5 af npn high current
bc308
bc413 x 7
bc548 x 12
bc558 x 4
bc517
c711 x 6
c829 x 2
s9014 c 117 npn
md8003 x 4 NPN SILICON EUAL TRANSISTOR

ka2212 audio amp
tba120 The TBA120 Series ICs provide a high-gain limiting IF amplifier and a quadrature coincidence detector in one package. These ICs are primarily intended for extraction of TV intercarrier sound, which (in Europe) is frequency modulated onto a 5.5MHz or 6MHz subcarrier.
mm74c14n cd40106bcn x 2 CMOS HEX BUFFERS/CONVERTERS
lm747cn x 4 Dual Operational Amplifier
mc1486l 7643  ?
74ls132n8036 x 2 QUAD 2-INPUT NAND GATE
74ls02 QUAD 2-INPUT NOR GATE

an6516n Monostable Multivibrators
sn74121n x 2 MONOSTABLE MULTIVIBRATORS WITH SCHMITT-TRIGGER INPUTS
sn74123n RETRIGGERABLE MONOSTABLE MULTIVIBRATORS


so yeah whats up with the multivibrators? anything usefull i could turn into something cool on the 16 pin chips?

Welcome to the forum! What is your background ?
Some of those parts are pretty common most I don't recognize. I am guessing these are new parts.
  If you just want to build something you could easily get a bunch of fuzz pedals made with those transistors most buzzy pedals are not picky about parts. Do you have a HFE tester ? That may be a good way of sorting through them if you can never get a hold of the data sheets.
Class A booster , Dod 250 , Jfet booster, Optical Tremolo, Little Gem 2,  mosfet boost, Super fuzz , ESP stand alone spring reverb red Llama omni-drive , splitter blender ,

NEVER use gorilla glue for guitar repairs! It's Titebond , Elmers, or Superglue

* these are all NPN's...at any rate if the DMM has Hfe, stick 'em in and test their polarity and Hfe. The 2n2222 are probably low Hfe and may be good for Si FF Q1 [or 2]------
8 pin chips
6562 op amp
741 op amp  DISTORTION +
lm301 x 2 op amp
748 x 2 op amp
1458 Dual General-Purpose Operational Amplifier..this and a couple NPN's could be the actives in a Neutron Filter.lm308 Operational Amplifier
  Perhaps the lm301...the LM308 is a compensated OA, used in RATs
  I never messed around with multivibrators, someone'll probably chime in, I've seen them used around here.

MD8003  ;D

ive looked all over for those.
IIRC those are matched transistors, good for input differentials in power amps...
Look at it this way- everyone rags on air guitar here because everyone can play guitar.  If we were on a lawn mower forum, air guitar would be okay and they would ridicule air mowing.

741's: dod250, rustdriver

301's can be substituted for 308's in the rat
When your life is over, will any of this STUFF really matter?

Thanks for some replys guys, my background? Well im not an electrical engineer, i did highschool physics, ive been making pedals for about 2 months now cause its winter, done about 10 distortions, a couple of phasers, tremilos, compressors, delays, univibe, cuts out some resistors and caps from the gain stage of my tube amp. So yeah, i know schematics but nothing fancy like calculating/programing. Ive tryed designing a pedal from scratch but failed :P, but i always breadboard and tweek the values.

So yeah I'd like to know more about these nand gates cause i just found this youtube clip:

well I just found some tutorials so ill see what i come up with..
