Ok so this is the amp history...Herbert was bought from Diezel by my friend Rob in 2007 or 2008, I'm the second owner. The Herbert was originally wired for 100v because Rob was playing gigs in Okinawa, Japan. After he bought his other amp the Herbert was just sitting around and so he sold it to me at a pretty good price to include shipping and changing the internal connections on the transformer so I could plugin the 120v, here in the states. So I got the amp in March 2012....I play the amp in my studio when I can and started to have problems last year with excessive volume drop. I posted a message and the suggestions I got where to get new tubes. So I got a set of tubes, preamp and power, changed them and reset the bias, played it a couple time and had the problem reoccur once. I'm going to try to post a video in the post but it i can't get it to work the title is: My Diezel Herbert is sick
Any constructive suggestions are appreciated,
