  11. Circuit Diagram of D313 Power Amplifier

    dear .. there is no such circuit found using D313. It may be 2SD313 or relevant transistor 2N3055 or 2SD880. Each channel having built around 2 nos. 2SD313 transistors and, of course, for stereo applications 4 Nos. are used. The power supply is 12-0-12, 5 Amp rating and can deliver 200Wrms as is printed by mfrs.(but actually may be around 30 Watts). Do you need this circuit. truly yours, Shamim.
