在电子管收音机的6P1管座下,引出两根线,加装一只插座(DZ),这样,在收音机收听广播时,又可以给干电池充电。一举两得,既方便又实用。具体接线如图所示。在交流电子管收音机功放管的阴极电阻放大线路上,由于阴极电阻的降压使用,使其两端产生一个电位差,一般功放管6P1阴极电阻两端均存在6V左右的直流电压。所以无线电爱好者往往利用这一稳定的直流电,来检修晶体管收音机,或给其它动力供电和充电。
Under the 6P1 tube mount of the tube radio, draw two wires and install a socket (DZ) so that the batteries can be recharged while the radio is listening to the radio. Serve two purposes, both convenient and practical. Specific wiring as shown. In the AC tube amplifier amplifier cathode resistance amplification circuit, the use of the cathode resistance of the step-down, so that the two ends of a potential difference, the general power amplifier tube 6P1 cathode resistance at both ends of the existence of about 6V DC voltage. So radio enthusiasts often use this stable DC to troubleshoot transistor radios or power and charge other power sources.
