Hi, i wrote to Haden and he helped me a lot. I'm trying to bring the amp back to its original state. Thank you! Best Kaya
Hello Paul-2007, I have a Phono Pre from Haden Boardman for half a year and I found out that this is your old preamp. What exactly was done there? was only the power supply changed or other things? Unfortunately I have a loud hum and can not get it solved. I would be very grateful for an answer! Greetings from northern Germany. Kaya
