Default HRII to operate with 55V - a higher power HRII

This circuit was assembled and tested, but the board layout was never assembled, it may have bugs, may have errors or mistakes...if you decide to use it you should know that you may check each part in order to find for mistakes.

Board layout is not guaranteed because not tested, not build, not checked...but schematic was built, was checked and was tested, works fine and it is guaranteed.

regards,

Carlos

Default Warning! .... untested boards can be a trouble

Sometimes has errors on them...sometimes oscilates.... i cannot guarantee this board..was checked many times..by me and by Todd Johnson...but we use to be blind to mistakes (alike everybody)

Carlos
