    the rms volt of transformer is 348v , I cant reach the cap due to parallel installed pcb ,measured 450v from 10m90s and c2ms drain by multimeter. On monday I will bring oscilloscope to studio.

    I will replace all bridge diodes by stth512s on Monday, just noticed something. I bought smt k389 from taobao , they are made by linear.sys , cost 45rmb or 5 pounds , mint choice.

    Replaced STTH512 by infineon IDH10S120 on PSU ..... Hmmmm.....no output voltage. I'v chosen this diode for making a "more carbon version KG Carbon", and the performance of IDH10s120 way better than STTH512 on paper but donno what happened. I bought some SMT version of 2SK389 for better thermal coupling and way cheaper......hope it works.
