Combines advantages of differential output stage and high-impedance JFET input stage. Silicon input diodes provide crude overload protection for input, while Tr2 acts with Tr1 for level-shifting as well as amplifying. R1 is used to set quiescent output voltage of Tr2 at about 15 V; this setting is critical, and may require multitum pot. Article gives setup procedures.-G. A. Johnston, Deflection Amplifier for Oscilfoscopes, Wireless World, April 1975, p 175.
