Michael - First of all, on the NeoPak/Shuttle 6.0, there is no solid state channel or signal path. It's a tube preamp only.
Does that mean that in case of a tube failure I won't be able to run the amp solid state only?
I don't really care for the peamp tube but I figured I could just 'ignore' it by isolating it from the signal path. That doesn't seem possible then.
