Ok Nomad 100 owners. 45 views and not one reply. This is the kind of thing that gives the Nomad's a bad reputation. LOL
It's actually a serious question. If you have a Nomad 100, please look at the back where the fuse is and post the amp rating.
I have a theory that some of these might be different... (either higher or lower from the factory specs) leading to higher/lower plate voltage on the tubes... meaning that they sound different.
