The Long-Tail Pair

General

The Marshall/Fender phase inverter is commonly known as a "long-tail pair", or "Schmitt" type phase inverter, or phase splitter (actually, the original Schmitt inverter was a differential pair with a large "tail" resistor; the "standard" guitar amplifier phase inverter is a self-biased version of this circuit that works better with positive-only power supplies and...

What Is "Blocking" Distortion? - Aiken Amps

What Is "Blocking" Distortion?

General

If your amp has a particularly bad sounding "cutting in and out" kind of distortion (commonly referred to as "farting out"), it is likely suffering from what is known as "blocking" distortion (not the Radiotron Designer's Handbook definition of blocking, but the more esoteric Norman Crowhurst definition). Blocking occurs when  the output tube grids are...
