As a guide:
Murata Power Solutions’ 7805SR-C (5V output), 7812SR-C (12V output).
Consult the Murata datasheet and make sure you know your 5V regulator from your 12V regulator. The 7812SR-C will not work below a 15V input level. So you would have to be in Caiman territory if you want to do this mod and spend that sort of money.
A cheaper solution might have been the Leo mod, but I think he has put that aside due to the complexity of it and the certain electronics skill required. Any slip ups and it's good bye TC-7520.
