Together with the CA2000 and the (much underrated!) CA-F1 one of Sansuiās finest preamps. The line amp board kept me busy for quite some time, repairing all the bad connections between the top- and bottom traces of the board. Like with the BA5000 and the AU20000 I have fitted cyan LED illumination for the meters.
The power supply board of a CA3000 suffers from a similar problem as the preamp power supply board of an AU20000; resistors that get too hot and damage the circuit board. The proper way to solve this problem is to fit metal replacements on the inside of the adjacent inner panel for cooling and make a small cable loom to connect them to the appropriate positions on the circuit board.
