I'm new to this electronics thing, I rewired a few guitar switches in the past but lately decided to take a shot at pedal building. Stumbled across this thread and I'm glad I did, hopefully someone here can answer a couple of questions on scrounging for me.
I tore apart an old (1976) stereo for parts. Got the usual haul, pots, jacks, tons of multicolored wire, resistors, etc.. There are things that I know what they are but don't know what value.
There are quite a few diodes, not one has a label, just a red stripe to mark the anode. Is there a way to test them? Can I safely experiment with them, just dropping different ones into different circuits to see how they affect the sound?
There are some what appear to be tantalum capacitors, how can I veryify this? They are unlabeled.
