Circuit arrangement for improving loudspeaker reproduction in the consumer electronics, has impedance converter which is switched in electrical arrangement between anodes and control grids of output tubes

摘要

The circuit arrangement has an impedance converter which is switched in an electrical arrangement between the anodes (A3,A4) and the control grids of the output tubes. Other anodes (A1,A2) of the drive tube are connected with the bases (B1,B2) of the PNP-transistors (Tr1,Tr2). The emitters (E1,E2) are electrically connected with the series circuit. The collectors (K1,K2) are electrically connected with the control grids over a condenser.
