k 2496
Of course, I share everything with you...
He has a design which is completely stable at 100 kHz (or whatever choose)=
any circumstances and can therefore never become audible. They can be made=
portable, running from a 9 volt battery. Big as a cig pack.
I will ask if he can think of producing a number of such power supplies and=
the cost. Let me guess that he wants at least 2-3 times as much as a Rolls.
