Of course. The Alex 166 is called a "double tuba" by its makers, but in fact, the leadpipe goes to a switch valve which routes it either straight to the F set of valves and slides (the top in a stacked arrangement) or alternatively to the the CC "extensions" which are the second set of valves in a stacked arrangment. The plumbing then is routed back through the F valves. So, if you're playing valves 1234+5, you're routing the sonic path through 9 activated valves, each with 2 right-angle diversions! This makes the 6-valve Vienna F "brass accordion" sound downright attractive.
