In this inventive twist on the Klon, Robert Keeley switches out the "mythical" diodes for germanium transistors and offers ...

Testing germanium diodes. If you have an analog VOM, you may be surprised how high the short circuit current is on the Rx1 range. Mine runs 120mA. Note that this is sufficient current to destroy a ...

These days the envelope detector is a point contact diode such as a 1N34 Germanium diode. The resonant circuit passes a specific wavelength (or more specifically range of wavelengths depending on ...

The simple kit had a coil, a germanium diode, and a crystal earphone. ... The radio is simplicity itself, built on a wooden substrate with a very basic coil and capacitor tuned circuit.

When you apply forward voltage, Schottky and small-signal germanium diodes exhibit 0.2 to 0.25V and 0.35 to 0.45V drops, respectively. Figure 3 Two LED drivers operating in series or parallel let you ...

Crazy Tube Circuits has released a limited edition twist on its Unobtanium preamp/overdrive pedal, the amp-in-a-box drive twofer that has a Klon-style drive on one side, and two Dumble tube amp ...

Robert Keeley’s fingerprints are all over the Manis as the pedal boffin delivers a pedal that can serve faithful Klon tones, ...

Cork-sniffing circuit geeks might be interested to know that under the hood they will find NOS Carbon Comp resistors, NOS Philips, Sprague, GE or similar capacitors, NOS Germanium transistor and ...

Materials science researchers have demonstrated the first electrically injected laser made with germanium tin. Used as a semiconducting material for circuits on electronic devices, the diode laser ...
