Ensure that the front panel is free by pulling back the black cover. If it does not pull back, remove any remaining nuts or screws

Caution! While working in the amp head, use only one hand to ensure safety from electrical shock. This is a rare occurrence but only using one hand will protect you. Do not "ground" yourself by touching anything else with your other hand. Do not touch any unfamiliar components.

Locate the three pin connecters between the two PCBS. Gently unplug them by pulling straight up.

Remove the PCB from the amp head and set it aside to get ready for soldering
