In this inventive twist on the Klon, Robert Keeley switches out the "mythical" diodes for germanium transistors and offers diodes as a switchable option, and there's a bass boost feature too ...

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 ...

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 ...

This is a simplified circuit, but not by much. A practical diode switch usually works by maintain one side of the diode at a bias ... The early 1950s designer had to work with germanium point ...

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 ...

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 ...

The team has created the first modern germanium circuit – a complementary metal–oxide–semiconductor (CMOS) device – using germanium as the semiconductor instead of silicon. "Bell Labs created the ...

What if you were to swap out the mythical germanium diodes in a Klon Centaur overdrive pedal circuit and replace them with germanium transistors? Guitar effects pedal guru Robert Keeley asked that ...
