Hi, i'm using x3 live. I replaced u17, u18, u19, u20 to oap2134ua and opa4134u. After replacement, i touched u18, the opa4134ua was very hot and i could only hear noise from the headphone jack. U30(5va regulator) also was hot. Chip temperature was about 65°C. I think u18and u20 shorted, so i removed u18, u20 and i could heard guitar sound. And, +15V and -15V rail also shorted each other. But, u30(5va regulator) was still hot(65°C). is the regulator temperature normal?
