I seriously fried the small battery holder I was using for the reversing battery and melted one of my oscilloscope probes on the very hot reversing FET when fiddling with the oscillator circuit so I decided to make the output stage absolutely unable to go into forward and reverse at the same time by putting the two opto isolators back to back from one chopper amplifier to the other so only one of them can ever be on at a time - gets rid of some parts and adds a major safety improvement - bonus!

i认真油炸小电池匣，我使用为扭转电池和融化我的一个示波器探头就非常热扭转场效应管时，fiddling与振荡电路，所以我决定使输出的阶段，绝对无法进入正向和反向在同一时间，把两个光电隔离器背靠背从一菜刀放大器到其他，所以只有一个人能永远就在一个时间-摆脱部分，并增加了一个重大安全改善-奖金！
