Pirx Posted June 25, 2013 Report Share Posted June 25, 2013 (edited) Hi I am going to build energizer for Orpheus and Stax with LL9202AM. For Stax I will copy PSU Bias from T1. I wonder if I can use the same kind of PSU from T1 for Orpheus (with lower voltage of course)? I think so, but it could be very expensive mistake if I am wrong ... Any advice? http://farm3.staticflickr.com/2891/9135996783_0911380a26_o.jpg Edited June 25, 2013 by Pirx Quote Link to comment Share on other sites More sharing options...
spritzer Posted June 25, 2013 Report Share Posted June 25, 2013 The T1 bias supply is just a voltage doubler with a divider. Just set it to 500V and with a 10M ballast resistor and you'll be fine. Quote Link to comment Share on other sites More sharing options...
Pirx Posted June 25, 2013 Author Report Share Posted June 25, 2013 I wasn't sure how large should be this "ballast" resistor. Thanks Spritzer, I can always count on you Quote Link to comment Share on other sites More sharing options...
