0 (ZERO) Ohm Resistors (WTF)........

When I used them for some projects that I built, I always put them in sockets. There's also the problem that at the speeds stuff works at these days, the extra spacing is electrically significant. I remember playing with a tunnel diode in the 1960s when they were commercially available and they were quite difficult to stop oscillating! I think that accounts for why in hobby circles, their attraction was mostly as an oscillator. "WIreless mics", QRP transmitters on the amateur six metre band, oscillator/mixer in various receiver circuits. Offhand, I can't remember much of their use as amplifiers in hobby circles. The hobby magazines of that era were full of TD bugs. |

Are you saying that approximately zero is good enough? I'm not sure I understand your question, but the third band is the multiplier, and since the two first bands are zero, I've never seen any with more than 1 black band round the middle. |
