Pardon, are you feeding AC to the calc. or a version of DC such as half
rectified or full rectified? Are you regulating the supply? I know that the
calc dosn't draw much current but have you used a couple of smoothing
capacitors? Are you feeding the calculator it's 6Volts or somthing higher?
I suggest not to do this if any of the above hasn't been done.
