I have used this preamp in my home studio for more than 15 years and I haven't had any problems whatsoever with it. I just don't use it anymore so it needs to go to someone that will use it. The sound this preamp makes with the rack gear I used was outstanding.I hope whoever gets this preamp will enjoy it as much as I have. It is in excellent working and looking condition.
