Make before break with tube amps. I have some old early 1970s Lafayette Radio catalogs. They sold simple speaker selectors and there were two versions of each model listed. Tube or Solid State. The tube units were make before break and the SS units were break before make.
This is not a casual difference. A tube amp running unloaded for even a few hundred microseconds is enough to arc an output tube. Likewise two solid state amps connected in parallel again for even a few microseconds can destroy the output transistors.
