The main power transformer (toroid) part#
Replacement:
To replace the power transformer, it is necessary to remove the woofer from the cabinet. The mounting bolt and transformer itself is mounted on an internal brace; both are accessible through the woofer opening. Instructions for woofer removal can be found on the exploded view, page 7.
Troubleshooting:
To keep the circuit “live” while exposing the amplifier components, the amplifier cannot completely be removed and powered up outside the cabinet due to the power connections to the externally mounted transformer. Instead, an alternate method is to leave the amp cover in place and remove the four Phillips screws holding the amp ass’y to the amp cover. Then the amplifier can be partially removed for access, while maintaining the power connections. Unplugging the LED connection (red/black wires) at the PCB plug will allow the amp to be removed even further.
