Quoted from fusion301:Well I rebuilt all the components on the Eddy sensor board (except the resistors) including the new chip, POT etc., and the board is working as it should again. You can rebuild this board entirely for about 10-15 bucks, TDA0161DP chip will come from china however - end up being about $5 a piece.
utsource.net - gets my full approval for china made chips that you can not get in the USA.

Could you give more details on what you replaced besides the chip? Diodes? Pot? Mind started acting up and looks like I'll have to repair it as none are available as far as I can find. I emailed pinbits to see if they would have the auto adjusting ones again.
