I emailed Bogner and this was essentially their response. I don’t trust myself with poking around a live amp like that, so I told the tech about it and he’s gonna check it out.
Have a 2009 Uberschall Twin Jet that I turned on today, but I’m barely getting any volume. I put another quad of KT88s in there but I got no sound out of them at all. Checked all preamp tubes, but they are fine. Fuses are fine too. Any ideas on what to do next?
Spoke to someone I would assume to be Jorg (based on the accent) yesterday. He told me that they are really backed up with demand for the amp and that they don’t anticipate any more going out until July or August. He said Sweetwater has the most orders for the amp, but others have them too...
