I have a GenzBenz Streamliner . It’s maybe ten years old . The LED lights in the front panel had died , but the rest of the amp seemed to work wonderfully . Three tube preamp . Three gain stages , easy to dial in a clean , warm , or even distorted tone .
It had become a backup , but remained a lovely amp . 900 watts . I always had a shit ton of headroom . So when I heard that the guy that designed the amp was still servicing them I contacted him and sent it off to California .
Might have been one of my better gear expenditures last year . It came back with some factory upgrades and works like a brand new amp . I was over the moon to have the Class D rejuvenated .
I have two other Class D heads that see a lot of use . My little practise head that gets a daily workout , and my gig rig that just goes out the door on weekends .
