X xtr3m3 New member Oct 3, 2018 #1 I just installed the speedball kit and the small pcb voltages were all fine. When checking the big board I got these abnormal voltages: OA: 137V OB: 136V The resistance checks were all fine, as were the voltages for B+ and G. Also, all the leds lit up. Thanks for any help.
