keron Posted June 18, 2013 Report Share Posted June 18, 2013 I am searching for possible equivalents to use with this circuit.http://www.teddypardo.com/Resources/SuperTeddyReg.htmlThe purpose is to power a DAC with estimated current need of 1.5A at the maximum.They are low noise Nchannel JFETS.Being low noise is critical for the application I believe but it is just my guess.Please Help :) Quote Link to comment Share on other sites More sharing options...
Relayer110 Posted July 4, 2013 Report Share Posted July 4, 2013 Some equivalents:2SK1302SK1472SK1512SK162The pinouts of all of the above will be different to the 2SK363.Those FET's in the Teddy Pardo are being used as current regulators and would not be passing the 1.5A you mentioned.The transistors Q4 and Q7 will be taking the bulk of the current.I hope this helps.Regards,Relayer ;D ;D ;D Quote Link to comment Share on other sites More sharing options...
