This evening the SX-838 received a rebuild of the power supply board and power caps. First, the 8000uf power caps were replaced with premium Nichicon 1000uf radial leaded caps. The new caps being a fraction of the size were mounted horizontally in a new clamp.
The power supply board was completely recapped and retransistored. Nichicon PW series caps and Fairchild transistors were used in the rebuild. Below is the before and after photos of the board. Next up will be EQ, protection, and amp board.
