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.

Ahhh damit, I wrote the wrong one, I didn't mean to say KIA7810API, I meant the existing 7805. Sorry about that, I had them both written on the same bit of paper and mixed them up when I wrote the post, I was tired.

So I'm interested in swapping the existing 7805 reg for a Murata 7805SR-C.
So will any modifications be required for this?

The reason I chose this reg to swap first was because swapping the other one looked more complicated due to the differing input voltage requirements.

Thanks.
