我们在使用635型录音机的过程中,经常出现开机启动不可靠和启动瞬时走带抖动较大的问题。我们采取了一些措施,作了一点改动。这里主要介绍一下在机械部分加装皮轮启动延时继电器、在收带马达电路中加装稳定灯泡的措施。(请参看635型录音机机械系统图) We are using the 635-type recorder in the process, often appear unreliable start-up and start instantaneous transport jitter greater problems. We took some measures, made some changes. Here mainly introduces the mechanical part of the installation of leather start delay relay, closing the motor circuit with a steady light bulbs measures.
