So, this is not a TRA 500, it is an EST 500. I opened it up and saw some damage to the circuit board. It looks like a part fried, and one has even come completely disconnected on one side. The large orange piece is loose and the small blue trimpot is only connected on one end now. Can anyone help me identify and find a replacement for these? I know someone experienced to solder these in place, but I need to get the right pieces for them.
