all you need to validate is a multimeter.
If you have a scope and a function generator, it's easier.
How?
Setup a circuit that varies Ib of the transistor. Stick some sort of resistor on the emitter. Stick the X channel on the emitter and the Y channel on the collector. Stick your function generator on the collector and DC bias the transistor and sweep Vce essentially. Stick the scope in XY mode. Capture the waveform. Change Ib, capture again. Repeat.
If you don't have a scope and a AC source? Well just manually plot the IV curve for a few values.
Spritzer, did you ever get yours working properly?
I have some oscillation, no 'noise' though. I'm using Dale resistors in the batteries, as the Xicon are slightly inductive I have found. I think my issue is related to the position of the feedback resistors, and I haven't had a chance to verify that.
I'm sure this is another cocktail, but it turned out to taste nice, but kinda smells funny:
1.5 oz vintage bourbon
0.25 oz mandarine
peychauds
lump of sugar
lemon rind
old-fashioned prep
