Hi RATs, I put up a page for a new amp I built. http://www.timebanditaudio.com/Harald%20van%20Haaren%20Amp/vanHaaren300B.html If the link doesn't work go to my main page at http://www.timebanditaudio.com/timebandit.html and go to the bottom of the page. This one sounds really nice. Zero audible hum. Best regards, Raymond
