JCarcopo, when you use the switcher keep in mind that if a tube amp having output transformers is powered up and does not have speakers or equivalent load resistors connected to its outputs damage to the output transformers and/or output tubes can result. Especially if a signal is being provided to its inputs.
Presumably the switcher connects its unselected inputs to nothing.
