Long tailed pair amplifier

WebThis is a long-tailed-pair phase inverter! In its most basic form, an LTP is a differential amplifier with one of its phases connected to AC ground. The 2.35kΩ resistance, representing two 4.7kΩ resistors in parallel, provides the same DC conditions. WebThe long-tailed-pair phase inverter with negative feedback from the output transformer is one of the most ubiquitous architectures in guitar amplifier electronics. A signal from a tap in the output transformer secondary drives the feedback input to the phase inverter to counteract the amplified signal. The resulting closed-loop gain, measured ...
