    • Remove the 8 coarse thread wood screws and gently pry the plate out

    • Carefully remove the 3 knobs and the 1 screw between the 2 10A fuses. then the plastic face should pop off

    • Crossover / Gain

    • Power Supply and output FET's

    • Power Supply Transformer

    • Output Filters

    • The 2 boards are held together by 4 screws on the edges of the PCB, gently pull them apart, they will only be held together by pin headers. Here you can see the 2 output filters and the power supply step up transformer

    • The board with the FEMALE pin headers is the front board with the plugs on it. the crossover network consists of JRC 4850's

    • There are 4 of these "GA7E1S" FET's that i cant find any info on. i would assume by looking at the boards that 2 are the power supply and the other 2 are the outputs

    • There are NO heatsinks anywhere in this unit which i find amazing. but the FETS most likely use the massive copper planes on the board as the heatsink

    • More jelly bean logic around the board

    • The custom 12" driver. it appears to be a DVC driver, but it just a SVC with 2 pairs of leads going to it
