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 ...

R10 provides about 1mA of current to their emitters. If the bases of Q6 and Q7 are at the same voltage, then they will each conduct half that current. The current through Q6 is just enough to turn on Q5.
